Search for “Part 135 international operations requirements” and you will find a frustrating gap: plenty of pages tell you the documents to carry aboard, almost none lay out the authorizations you have to hold before the trip is legal. Those are two different questions. A Part 135 certificate makes you a commercial operator — but it does not, by itself, let you cross an ocean, fly the North Atlantic tracks, or even cruise at FL370 over Canada. Each of those capabilities is granted separately, by the FAA, as a line in your operations specifications.
This guide walks the capability stack. We anchor it in the regulations we can quote — 14 CFR §91.703 (operating a U.S. aircraft outside the U.S.), §91.706 and §91.180 (RVSM) — and we frame the OpSpec/LOA authorizations and the FAA’s operations specifications system honestly as FAA guidance and authorizations (Order 8900.1, the B-series OpSpec notices), not as CFR sections. They are not the same thing, and inventing a CFR cite for an OpSpec is exactly the kind of error this guide exists to prevent.
One framing note up front. This post is the capability half of going abroad. Its companion — the documents and records you must carry for international operations — is the paperwork half (the airworthiness and registration certificates aboard, the FCC station license, the ICAO journey log, customs and overflight permits). You need both. Read them as a pair: this one is the authorizations you must hold; that one is the documents you must carry.
Certificate vs. Capability: What Part 135 Alone Does Not Buy
Part 119 certification (which is what makes you a Part 135 air carrier or commercial operator under 14 CFR §119.1) establishes that you may carry persons or property for compensation. It says nothing about where or in what airspace. Those are added as authorizations. Here is the gap between holding the certificate and being able to fly a specific international trip.
What the Part 135 certificate gives you
- Authority to operate for compensation or hire (per §119.1).
- A baseline set of OpSpecs for your domestic operation.
- Your kinds-of-operation authority (e.g., VFR/IFR, day/night).
- Your authorized aircraft and basic en route authority.
What you must add to go international
- An authorized en route area that covers the destination region (B050).
- Navigation authority for oceanic/remote airspace (B036), built on RNP specs.
- RVSM authorization for the FL290–FL410 band (B046).
- Special-area authority such as North Atlantic HLA, where applicable.
- Crew area-qualification and aircraft equipment to match.
This is the same “the certificate is not the whole story” lesson that runs through Part 135 generally — it shows up in required management personnel, in the SMS framework, and in the difference between holding a certificate and surviving a surveillance audit. International capability is one more layer the certificate does not include by default.
A common and expensive assumption
Operators sometimes book an international charter on the assumption that “we’re a 135, we can fly anywhere.” If the OpSpecs do not yet include the en route area, RVSM, or oceanic authorization the route requires, the trip is not legal — and adding an authorization is an application-and-approval cycle with the FAA, not a same-day fix. The capability has to exist before the trip is sold. That lead time is why operators track the status of each authorization, not just its existence.
The International OpSpec Stack, Piece by Piece
These are the authorizations that most commonly make up an international Part 135 capability. The exact OpSpec paragraph numbers and prerequisites are set by FAA guidance and can be revised, so treat the codes below as the current common references and confirm your specific authorizations against your OpSpecs and your POI. We cite the FAA notices that define them.
| Authorization | What it grants | Reference |
|---|---|---|
| OpSpec B050 | Authorized areas of en route operations, limitations, and provisions — the geographic regions you may operate in. Going to a new part of the world starts here. | FAA OpSpec / Order 8900.1 |
| OpSpec B036 | Oceanic and remote continental navigation using long-range navigation, built on RNP navigation specifications (e.g., RNP 10 / RNP 4). The basic authority for crossing oceans and remote airspace. | FAA Notice N 8900.350 |
| OpSpec B046 | Reduced Vertical Separation Minimum (RVSM) airspace — the FL290 to FL410 band, where the aircraft must meet appendix G and the operator must be authorized. | FAA Notice N 8900.376 |
| North Atlantic HLA | Operations in North Atlantic High Level Airspace. Oceanic authority (B036) is typically a prerequisite, and the aircraft must meet a qualifying RNP navigation specification. | FAA guidance (NAT HLA) |
| Data link / CPDLC | Controller-pilot data link and related communication/surveillance authority required in much oceanic and remote airspace, where applicable to the route. | FAA guidance |
B050 — your authorized en route areas
The foundation. OpSpec B050 lists the areas of en route operations your certificate is authorized for, with their limitations and provisions. A purely domestic 135 may have only domestic U.S. areas. Adding an international region — the Caribbean, the North Atlantic, Europe, the Pacific — means amending B050 (and adding the navigation and special-area authorizations the region requires). When an inspector asks "are you authorized to be here," B050 is the answer.
B036 — oceanic and remote continental navigation
Most international routes leave radar/VHF coverage and enter airspace that requires performance-based navigation. OpSpec B036 (see FAA Notice N 8900.350) authorizes oceanic and remote continental operation using long-range navigation, predicated on meeting RNP navigation specifications such as RNP 10 or RNP 4. It generally rests on dual long-range navigation systems installed and operational. B036 is frequently a prerequisite for North Atlantic operations.
B046 — RVSM authorization
Between roughly FL290 and FL410, the world runs on Reduced Vertical Separation Minimum. OpSpec B046 (FAA Notice N 8900.376) is the authorization to operate there. The aircraft must meet the altitude-keeping equipment and performance standards of 14 CFR part 91 appendix G, and the authorization is backed by §91.180 domestically and §91.706 for operations outside the U.S. Because nearly every jet international trip cruises in this band, B046 is effectively a baseline international authorization.
North Atlantic HLA & special-area authorizations
Specific airspace gets its own authorization. North Atlantic High Level Airspace (the organized track system region) requires a dedicated authority, with oceanic navigation (B036) as a typical prerequisite and a qualifying RNP navigation spec. Other regions and procedures — special areas of operation, MNPS-legacy concepts, data link / CPDLC — carry their own authorizations. Which ones you need is entirely a function of your routes.
Authorizations chain — prerequisites matter
These authorizations are not independent checkboxes; they build on each other. Oceanic and remote authority (B036) is generally a prerequisite for North Atlantic High Level Airspace authority, and the aircraft has to meet the underlying RNP navigation specification before either is granted. That chaining is why “just add the North Atlantic” is rarely a single step — you often have to establish the navigation capability first. For the RVSM piece specifically, the equipment and altimetry-system test records behind B046 are themselves a tracked record set, which we cover in our RVSM altimeter and transponder records guide.
Is One of Your International Authorizations About to Lapse?
OpSpecs get amended, RVSM equipment records expire, navigation databases age out.

Run the FAA Readiness Score — FreeThe Regulatory Floor: §91.703 and §91.706
The OpSpecs are how the FAA grants capability. The CFR is the floor those capabilities sit on. 14 CFR §91.703 — “Operations of civil aircraft of U.S. registry outside of the United States” — is the master rule. It does not list authorizations; it establishes which rules govern where.
| Paragraph | When / Where | What Governs |
|---|---|---|
| §91.703(a)(1) | Over the high seas | Annex 2 (Rules of the Air) to the Convention on International Civil Aviation, plus §§91.117(c), 91.127, 91.129, and 91.131 |
| §91.703(a)(2) | Within a foreign country | The regulations relating to the flight and maneuver of aircraft in force in that country |
| §91.703(a)(3) | Otherwise | Part 91, so far as not inconsistent with the foreign rules or Annex 2 — except §§91.117(a), 91.307(b), 91.309, 91.323, and 91.711 |
| §91.703(a)(4) | In RVSM airspace | The requirements of §91.706 |
| §91.703(a)(5) | Aircraft subject to ICAO Annex 16 | Carry aboard the documents demonstrating noise/emissions compliance |
RVSM: §91.180, §91.706, and OpSpec B046 together
RVSM is the cleanest illustration of how the CFR floor and the OpSpec authorization interlock. §91.180 sets the general rule: to operate in RVSM airspace, the operator and the aircraft must meet the minimum standards of appendix G, and the operator must be authorized by the Administrator or the country of registry. §91.706 carries that same appendix G and authorization requirement into RVSM airspace outside the United States — which is most of the RVSM airspace an international trip will see.
The authorization §91.180 and §91.706 require is granted to a Part 135 operator through OpSpec B046 (FAA Notice N 8900.376). So the full picture is: the CFR says “be equipped to appendix G and be authorized,” and B046 is the document that proves you are. That is why we describe B046 as an FAA authorization, not a regulation — and why the equipment and altimetry records behind it are a record set you keep current.
Annex 2 is incorporated by reference
§91.703(b) incorporates ICAO Annex 2 (Rules of the Air) into the regulation by reference — which is how an international treaty annex becomes enforceable as a U.S. rule over the high seas. The practical reading for a Part 135 crew: your U.S. certificate and your Part 91 obligations travel with you, but over the oceans the international rules of the air apply, and inside a foreign country that country’s flight rules take precedence. Your OpSpec authorizations are what let you legally be in that airspace in the first place.
How You Actually Get International OpSpecs
International authorizations are not a form you submit once. They are amendments to your operations specifications, granted by your principal operations inspector (POI) through the FAA’s operations specifications system, following the guidance in FAA Order 8900.1. The general shape of the process:
Establish the equipment and aircraft capability
The aircraft must be equipped and approved for the navigation specification and airspace — RVSM-compliant per appendix G for B046, dual long-range navigation for oceanic B036, data link where required. Equipment without the supporting approval records does not count.
Update manuals, procedures, and MEL
Your operations manuals, training program, and minimum equipment list have to address the area, navigation specs, and contingency procedures for the airspace (oceanic contingency, lost-communication, etc.). The FAA reviews these as part of granting the authorization.
Qualify the crews for the area and operation
Crews need the area knowledge and training the airspace requires (oceanic procedures, ICAO differences, the destination region). Area-qualification records become part of the evidence — and a recurring, expiring record set.
Apply through your POI; the FAA amends the OpSpecs
You request the authorization; the FAA evaluates equipment, manuals, training, and any required validation, then amends your OpSpecs to add it — sometimes with limitations or conditions. The authorization exists only once it is issued in your OpSpecs.
OpSpecs are a living document — and can be conditioned or suspended
Because authorizations are amendments to a document the FAA controls, they are not permanent. They can be limited, conditioned, or suspended — for example if the supporting equipment records, navigation-database currency, or crew qualifications fall out of date. That is the whole reason an authorization belongs on a version-and-expiration calendar: holding it last year does not prove you hold it today. The same surveillance posture that examines your other records will examine whether your international authorizations are still supported — see how to prepare for a Part 135 surveillance audit.
Authorizations vs. documents vs. operational control
Keep three things separate. Authorizations (this guide) are the OpSpec capabilities you hold. Documents (the international documents and records guide) are the physical papers you carry — certificates, FCC license, journey log, permits. Operational control — who is actually running the flight — is a separate question that turns up whenever a Part 135 trip blurs into private use; see Part 91 vs. Part 135 compensation or hire and the flight department company trap. Conflating them is how operators get the authorizations right but still end up in trouble — including the grey-charter zone.
Tracking the Authorization Stack as Audit-Ready Documents
Holding international authorizations is one thing; proving they are current and supported is another. Each authorization in the stack is backed by records that expire on their own clocks. Here is the document file an international Part 135 capability generates — the thing that has to be assembled and current when an inspector or a foreign authority asks.
The International Authorization File
Current OpSpecs showing the authorized en route areas (B050) that cover your routes — the controlling document for "are you allowed here."
Oceanic and remote continental navigation authorization (B036) and the RNP navigation-specification approval behind it.
RVSM authorization (B046) plus the appendix G equipment approval and the altimetry-system / transponder test records that keep it valid.
North Atlantic HLA (or other special-area) authorization and its prerequisite navigation authority.
Data link / CPDLC authorization where the route requires it.
Navigation-database currency records and the equipment status the navigation specs depend on.
Crew area-qualification and training records for the regions and procedures flown (recurring, expiring).
The aircraft equipment list / MEL status supporting each authorization.
This is the capability file. For the documents that physically ride along on the trip — airworthiness and registration certificates, the FCC station license, the ICAO journey log, customs and overflight permits — see the companion international documents and records guide.
How FileFlo Fits the Authorization Stack
FileFlo is a compliance document intelligence platform — a read-only proof layer that sits alongside your existing records. For international operations it classifies and version-controls the authorizations and their supporting evidence: the current OpSpecs (B050 areas, B036 oceanic/remote, B046 RVSM, special-area authorizations), the appendix G equipment and altimetry records behind RVSM, navigation-database currency, and crew area-qualification records. Each is tracked as a document with its own expiration, surfaced 90/60/30 days before it lapses, and assembled into an inspector- or ramp-ready binder on demand. Because OpSpecs are a living document that gets amended, FileFlo version-controls them so you can prove which authorization was in force on which date.
What FileFlo does not do: it does not apply for or amend your OpSpecs, obtain LOAs, decide whether your aircraft is RVSM- or RNP-compliant, qualify your crews, interact with your POI, file customs or eAPIS, obtain overflight permits, or give legal advice. It does not run your operation or make the operational-control call. It keeps the proof that your authorizations are current and supported organized and audit-ready; the authorizations themselves stay between you and the FAA. For how long to keep the records behind them, see our RVSM records guide and the broader management-personnel context in the director of safety and SMS requirement.

Frequently Asked Questions
Can a Part 135 operator fly internationally?
Yes — a Part 135 certificate holder can fly internationally, but the certificate alone is not enough. International operations are unlocked by specific authorizations the FAA grants in your operations specifications (OpSpecs): an authorized en route area that includes the foreign region (OpSpec B050), the navigation authority for the airspace you will cross (for example oceanic and remote continental operations under OpSpec B036), and any special-airspace authority such as RVSM (OpSpec B046) or North Atlantic High Level Airspace. On top of those, 14 CFR §91.703 requires you to comply with ICAO Annex 2 over the high seas and with the rules of each foreign country you operate in. So the honest answer is: the certificate gets you commercial authority; the OpSpecs plus §91.703 plus each state's permission get you across the border.
What authorizations do you need to fly Part 135 internationally?
There is no single international permit. Practically you assemble a stack: (1) an authorized area of en route operations that covers the region (OpSpec B050); (2) the navigation authorization for the airspace — oceanic and remote continental operation under OpSpec B036 is the common one, built on RNP navigation specifications; (3) RVSM authorization (OpSpec B046) for the FL290 to FL410 band that most international routes cross, which the regulation backs with 14 CFR §91.706; (4) any special-area authorization such as North Atlantic High Level Airspace; and, depending on equipment and route, data link / CPDLC and MNPS-legacy authorizations. Each of these is a line item in your OpSpecs, issued by your FAA principal operations inspector. FileFlo tracks each authorization as a document with its own validity so none of them quietly lapses; it does not apply for them on your behalf.
What is OpSpec B046 and do I need it for international flights?
OpSpec B046 is the FAA authorization to operate in Reduced Vertical Separation Minimum (RVSM) airspace — see FAA Notice N 8900.376, "OpSpec/MSpec/LOA B046, Operations in RVSM Airspace." Between roughly FL290 and FL410, most of the world's en route airspace is RVSM, so an international trip almost always crosses it. To hold B046 your aircraft must meet the equipment and altitude-keeping performance standards of 14 CFR part 91 appendix G and you must be authorized by the Administrator; 14 CFR §91.706 ties the international RVSM requirement back to those standards. B046 is not itself an international authorization — it is an airspace authorization — but it is one of the authorizations you almost always need before an international flight is legal at typical cruise altitudes.
What does 14 CFR §91.703 require for operations outside the United States?
14 CFR §91.703, "Operations of civil aircraft of U.S. registry outside of the United States," sets a layered hierarchy rather than a checklist. Over the high seas you comply with Annex 2 (Rules of the Air) to the Convention on International Civil Aviation and with §§91.117(c), 91.127, 91.129, and 91.131 (§91.703(a)(1)). Within a foreign country you comply with that country's regulations relating to the flight and maneuver of aircraft (§91.703(a)(2)). Otherwise you comply with Part 91 so far as it is not inconsistent with the foreign rules or Annex 2, with a short list of carve-outs (§91.703(a)(3)). RVSM operations add §91.706 (§91.703(a)(4)), and aircraft subject to ICAO Annex 16 carry noise/emissions documents aboard (§91.703(a)(5)). The rule is the legal floor; your OpSpec authorizations are how the FAA grants you the capability to meet it.
Do you need RVSM authorization to fly internationally?
Almost always, yes — not because RVSM is an international rule, but because the altitudes international flights cruise at are RVSM airspace. 14 CFR §91.180 requires, for RVSM operations generally, that both the operator and the aircraft meet the minimum standards of appendix G and that the operator be authorized by the Administrator or the country of registry. For operations outside the U.S., §91.706 carries the same appendix G and authorization requirement into foreign and oceanic RVSM airspace. The FAA grants that authorization to a Part 135 operator through OpSpec B046. If your route stays below the RVSM band you can skip it, but for jet operations crossing oceans or continents, RVSM authorization is effectively mandatory and is a tracked, expiring capability.
Can a Part 135 operator fly to Canada, Mexico, or the Bahamas?
Yes, with the right authorizations and paperwork — and these nearby destinations are where many Part 135 operators first go international. The capability side still applies: your OpSpecs must include an authorized en route area that covers the destination (OpSpec B050), and depending on routing and altitude you may need RVSM (B046) and oceanic/remote authorization (B036) — a Bahamas trip, for instance, crosses water and often the RVSM band. The compliance-document side adds the items §91.703 and the FCC rules bring in (covered in our companion guide), plus each country's customs, immigration, and permit requirements. The point: even a short hop to Canada is governed by the same authorization framework as a transatlantic flight — just fewer of the pieces.
How do you get international operations specifications (OpSpecs)?
International OpSpecs are issued by your FAA principal operations inspector (POI) through the agency's operations specifications system, following FAA Order 8900.1 guidance. The process is an application-and-approval cycle, not a form you file once: you demonstrate that the aircraft is equipped, that your manuals and training address the airspace and navigation specifications, and that your crews are qualified for the area and operation; the FAA then amends your OpSpecs to add the authorization. Prerequisites chain — for example, oceanic authority (B036) is typically a prerequisite for North Atlantic High Level Airspace authority. Because the authorizations are amendments to a living document, they can be limited, conditioned, or suspended, which is exactly why they belong on an expiration and version calendar. FileFlo version-controls the OpSpec document; it does not interface with your POI for you.
Where does FileFlo fit in Part 135 international operations, and what does it not do?
FileFlo is a compliance document intelligence platform — a read-only proof layer that sits alongside your records. For international operations it classifies and version-controls the authorizations and their supporting evidence: the current OpSpecs (B050 areas, B036 oceanic/remote, B046 RVSM, special-area authorizations), the appendix G RVSM equipment and altimetry-system records behind B046, the navigation-database currency and equipment records the navigation specs depend on, and crew area-qualification records. It tracks each as a document with its own expiration and surfaces what is lapsing 90/60/30 days out, then assembles an inspector- or ramp-ready binder on demand. It does not apply for or amend your OpSpecs, obtain LOAs, decide whether your aircraft is RVSM-compliant, interact with your POI, file customs or permits, or give legal advice. It keeps the proof of your authorizations organized and current; the authorizations themselves stay between you and the FAA.
Keep Your International Authorizations Audit-Ready
FileFlo classifies 600+ aviation document types against the governing rule, version-controls your OpSpecs, and tracks the records behind each authorization 90/60/30 days out — the B046 RVSM equipment and altimetry tests, the B036 navigation approvals, crew area qualifications — then generates ramp- or inspector-ready binders on demand.
