Direct Answer — Part 380 Public Charter vs Part 135
A public charter stacks two different regimes. 14 CFR Part 380 is a U.S. Department of Transportation (DOT) economic regulation governing the charter operator — an indirect air carrier that forms the group, sells the seats, and protects passenger funds. 14 CFR Part 135 is an FAA operating rule governing the direct air carrier that actually flies the aircraft (crew, maintenance, operational control, records). 14 CFR 380.2 defines a Public Charter as “a one-way or round-trip charter flight to be performed by one or more direct air carriers that is arranged and sponsored by a charter operator.” So on a typical public charter the company you book with (Part 380) is not the company flying the plane (Part 135, sometimes Part 121). Part 380 does not lower the FAA safety standard. The live policy debate — the so-called “public charter loophole” — is about whether high-frequency, schedule-like public charters flown under Part 135 should instead meet the stricter Part 121 standard; the FAA issued a Notice of Intent on August 24, 2023, and DOT/FAA described further long-term actions on September 22, 2025.
This is a regulatory-gray, fast-moving area — get aviation counsel
Public charter structuring sits at the intersection of FAA safety rules and DOT economic licensing, and the relevant definitions are actively under FAA/DOT review. This article explains the framework and the records side so you can operate transparently. It is not legal advice, and FileFlo does not represent you to the FAA or DOT, opine on whether your structure is lawful, or guarantee any outcome. Before you launch, broker, or rely on a public charter program, talk to a qualified aviation attorney and verify the current rule status.
Two Layers, Two Regulators: The Heart of the Confusion
Almost all of the confusion about public charters comes from collapsing two separate things into one. In U.S. aviation, who is allowed to sell you transportation (economic authority, regulated by DOT) and under what safety rules the aircraft is flown (operating authority, regulated by the FAA) are governed by different bodies of law. A public charter is simply a particular way of combining them.
Layer 1 — DOT economic (Part 380)
The charter operator (a Public Charter operator, which is an indirect air carrier) forms the group, holds out and sells the seats to the public, and is responsible for the consumer-protection rules — advertising substantiation and the depository/escrow handling of passenger funds. This is 14 CFR Part 380, administered by DOT.
Sells the seats · Holds the funds · Does NOT fly the plane
Layer 2 — FAA operating (Part 135)
The direct air carrier holds the FAA certificate and actually operates the aircraft: airworthy equipment, qualified and current crew, an approved maintenance program, operational control, and the required records. On most public charters that carrier flies under 14 CFR Part 135 (on-demand); larger ones may use Part 121.
Flies the plane · Holds the certificate · Owns the safety standard
What the regulation actually says
The definitions in 14 CFR 380.2 make the split explicit:
- Public Charter: “a one-way or round-trip charter flight to be performed by one or more direct air carriers that is arranged and sponsored by a charter operator.”
- Public Charter operator: an indirect air carrier authorized to engage in the formation of groups for transportation on Public Charters (defined separately for U.S. and foreign operators).
- Direct air carrier: a certificated commuter or foreign air carrier, or an air taxi operator registered under Part 298 (or a Canadian charter air taxi under Part 294), that directly operates aircraft under a certificate, authorization, permit, or exemption issued by the Department.
The DOT economic layer is its own world
Beyond Part 380, DOT economic authority for the air-taxi side lives in 14 CFR Part 298 (exemptions for air taxi and commuter air carriers), and broker conduct lives in Part 295. If you want the economic-authority picture on its own, see DOT economic authority & Part 298 air taxi registration.
How a Public Charter Is Structured, Step by Step
Here is the typical flow of a public charter, from the passenger’s booking through the flight. Notice how the booking entity and the operating entity stay separate throughout — that separation is the defining feature of the Part 380 structure.
The charter operator forms and sells the trip
A Part 380 public charter operator (an indirect air carrier) designs the trip — route, schedule, price — and holds it out to the public, selling individual seats. It is the consumer-facing brand most passengers interact with.
Passenger funds are protected
Under Part 380, the operator must handle passenger payments through the required consumer-protection mechanism (such as a depository/escrow or surety arrangement) so that money is safeguarded if the charter does not operate. Documenting this correctly is a core Part 380 obligation.
A direct air carrier is contracted to fly it
The operator contracts a certificated direct air carrier — usually a Part 135 on-demand operator, sometimes a Part 121 carrier — to actually perform the flying. That carrier holds operational control and the FAA operating certificate.
DOT filings are made where required
Depending on the type of charter, the operator files the prospectus/charter agreement and related materials with DOT and complies with the Part 380 advertising and disclosure rules. This is economic regulation, separate from anything the FAA requires of the carrier.
The carrier flies it under its FAA rules
The direct air carrier conducts the flight under its operating rule (Part 135 or Part 121): qualified/current crew, airworthy aircraft, approved maintenance, operational control, and the recordkeeping the certificate requires.
Why operators use the public charter structure
The appeal
- Lets a non-operating brand sell seats on flights it does not have to certificate or fly
- Lets a Part 135 carrier fill seats on point-to-point trips sold by a partner
- Enables published, schedule-like, per-seat service without a Part 121 certificate
- A long-standing, lawful DOT structure when the rules are followed
The tension
- High-frequency, schedule-like service can resemble a Part 121 airline
- The flying is under Part 135, not the stricter Part 121 standard
- Two parties (operator + carrier) must each keep complete records
- The defining definitions are actively under FAA/DOT review

Public Charter vs Direct Part 135 vs Part 121: Side by Side
It helps to see the three common shapes of for-hire passenger service next to each other. The key columns are who sells the seat (economic authority) and under what rule the aircraft is flown (operating authority).
| Dimension | Public charter (Part 380) | Direct Part 135 charter | Part 121 airline |
|---|---|---|---|
| Who sells the seat | Charter operator (indirect air carrier) under Part 380 — DOT economic | The certificated operator itself sells directly | The air carrier itself (scheduled/supplemental) |
| Who flies the aircraft | A separate direct air carrier (usually Part 135, sometimes 121) | The same Part 135 operator | The Part 121 carrier |
| Operating rule (FAA) | Part 135 (most commonly) or Part 121 | Part 135 on-demand | Part 121 (the most stringent) |
| Economic authority (DOT) | Part 380 (+ underlying Part 298/121 authority of the carrier) | Part 298 air taxi registration (typical) | Certificate of public convenience and necessity |
| Looks like an airline to a passenger? | Sometimes — that is the policy concern | No — individually arranged | Yes — it is an airline |
| Consumer-fund protection | Yes — depository/escrow under Part 380 | Contract-based; not Part 380 escrow | Airline ticketing rules |
The middle of that spectrum is exactly where the controversy lives. For the underlying operating-rule differences that drive everything in the table, read Part 91 vs Part 121 vs Part 135 (the closest sibling to this guide). And because the FAA distinguishes commuter from on-demand by schedule frequency, the line between them matters here too — see Part 135 commuter vs on-demand.
One trip can sit in two regimes at once
The single most important takeaway: on a public charter, “Part 380” and “Part 135” are not alternatives you choose between — they apply simultaneously to different parties. The operator is regulated by DOT under Part 380; the carrier is regulated by the FAA under Part 135. Confusing the two is how operators get the structure — and the records — wrong.
The FAA/DOT Scrutiny: The “Public Charter Loophole” Debate
In recent years the public charter structure has come under sustained FAA and DOT scrutiny because some public charters have grown into frequent, published-schedule, point-to-point per-seat service that resembles an airline — while the flying is conducted under Part 135 rather than Part 121. The agencies’ concern is a safety one: that comparable airline-like service should meet a comparable safety standard. The discussion below is proposed and evolving policy, framed cautiously and date-stamped — it is not a settled rule.
FAA Notice of Intent
The FAA announced a Notice of Intent to consider revising the regulatory definitions of “on-demand operation,” “supplemental operation,” and “scheduled operation.” The FAA explained that over roughly the prior decade, public charters had been offered in such volume, scope, frequency, and complexity that some had become difficult to distinguish from Part 121 air carrier operations — and that, to ensure an appropriate level of safety, the regulations that would otherwise govern such flights should apply, up to Part 121.
DOT/FAA describe further long-term actions
DOT and FAA outlined near-term and long-term steps, including potentially removing references to public charter operations and Part 380 from the regulatory definitions of scheduled, on-demand, and supplemental operations. An FAA Associate Administrator for Aviation Safety publicly indicated that if changes are made, there would be a window of at least three years before implementation. DOT also declined to opine definitively on whether commuter passenger operations under Part 380 constitute scheduled service, while leaving the door open to future rulemaking.
How the definitions actually draw the line
Why do those three definitions matter so much? Because 14 CFR 110.2 defines commuter operations by schedule frequency (at least five round trips per week on at least one route, in small aircraft) and treats certain passenger-carrying operations “conducted as a public charter” within the on-demand definition. Re-drawing where public charters fall among scheduled, on-demand, and supplemental is precisely what determines whether the stricter Part 121 framework attaches.
Sources: FAA Notice of Intent regarding the definitions of on-demand, supplemental, and scheduled operations (announced Aug 24, 2023); DOT/FAA aviation regulatory developments (Sept 22, 2025); 14 CFR 110.2 (operating definitions). Status as of June 15, 2026 — proposed/under consideration. Verify the current rule before relying on any structure.
“Loophole” is a headline word — the reality is more specific
Public charters are lawful, certificated operations flown by FAA-certificate holders; calling Part 380 a “loophole” is shorthand for a narrow structural concern, not a claim that the flights are unregulated. Whether a particular program is affected by any rule change — and what to do about it — is a fact-specific legal question. Do not restructure, wind down, or launch a program based on a blog post; get an aviation attorney’s read on your specific operation and the current rule status.
This scrutiny connects directly to the FAA’s broader enforcement focus on operational control and who is really running the flight. If your operation touches any gray area, two companion reads are essential: the FAA crackdown on illegal “grey” charter (where operational-control evidence decides outcomes) and charter broker compliance under 14 CFR Part 295 (because brokers, public charter operators, and direct carriers are easy to confuse and each carries distinct duties). It also pairs with the structural question of aircraft management company vs charter.
Who Keeps Which Records — and Where FileFlo Fits
Because a public charter involves two regulated parties, it generates two record sets. When the FAA or DOT asks questions — and in this climate they do — each party has to produce a complete, dated, retrievable record set for its side. Here is the split.
Direct air carrier (FAA / Part 135)
- Airman & medical certificates; training, checking, currency
- Duty-time and flight-time records
- Aircraft airworthiness, maintenance, and AD compliance
- Operational control / flight-release & weight-and-balance
Public charter operator (DOT / Part 380)
- Filed charter agreement / prospectus where required
- Advertising and disclosure substantiation
- Depository/escrow records for passenger funds
- DOT registration and authorization documentation
For the operating-side obligations in depth, see how to get a Part 135 certificate and our records-half guides on handling an FAA records request during an investigation and FAA fines for Part 135 paperwork violations. And because fractional and management structures get tangled up with charter, compare Part 91K fractional ownership compliance records and Part 135 vs Part 91K fractional.
FileFlo: the Operator Records Behind a Public Charter
FileFlo is a compliance document intelligence platform — the proof layer for your records. It does not represent you to the FAA or DOT, opine on whether your public charter structure is lawful, file an appeal, give legal advice, run your safety program, or guarantee any outcome. Those belong to you and to a qualified aviation attorney. What FileFlo does is keep the document set the FAA and DOT weigh — current, complete, immutable, and instantly retrievable — so that when a regulator asks, the records are a search away rather than a scramble.
- Classifies and indexes aircraft, crew, training, and maintenance records so you can produce everything for a specific flight, aircraft, and date range in minutes
- Tracks currency and expirations across crew and aircraft so fewer deviations happen in the first place
- Preserves an immutable, version-tracked history — the integrity that keeps a record set defensible
- Keeps the operator-side document set (filings, agreements, disclosures, fund-handling records) organized alongside the carrier-side operating records
- Generates an inspector-ready, dated records index on demand, so an FAA or DOT request is answered, not feared
FileFlo classifies 600+ document types and manages records across Part 91, Part 135, and Part 145 operators. Pricing: Starter $89/mo, Professional $299/mo. 5-day free trial, no credit card required. FileFlo keeps the documents that prove compliance audit-ready — it is not an SMS, a dispatch/flight-operations system, an attorney, or a guarantee of any FAA or DOT outcome.
Frequently Asked Questions
What is a public charter flight?
A public charter is a one-way or round-trip charter that a charter operator arranges, sponsors, and sells to the public, with the actual flying performed by a separate certificated direct air carrier. 14 CFR 380.2 defines a Public Charter as "a one-way or round-trip charter flight to be performed by one or more direct air carriers that is arranged and sponsored by a charter operator." In plain English: the company that takes your booking and sells you a seat (the public charter operator, an indirect air carrier regulated by the U.S. Department of Transportation under Part 380) is usually not the same company that flies the airplane (the direct air carrier, typically a Part 135 on-demand operator, sometimes a Part 121 carrier). Part 380 is a DOT economic-licensing regime layered on top of an FAA operating certificate — it is not itself an FAA safety rule.
What is the difference between Part 380 and Part 135?
They regulate two different things. 14 CFR Part 380 is a U.S. Department of Transportation economic regulation that governs the charter operator (an indirect air carrier) who forms the group, sells the seats, and holds the public charter agreement and the depository/escrow protections for passenger funds. 14 CFR Part 135 is an FAA operating rule that governs the direct air carrier actually flying the aircraft — its crew qualifications, maintenance program, operational control, and recordkeeping. A typical public charter therefore involves both at once: the Part 380 operator on the economic/booking side and the Part 135 (or Part 121) certificate holder on the safety/operating side. Part 380 does not lower or replace the FAA operating standard the aircraft is flown under.
What is a public charter operator?
Under 14 CFR 380.2, a Public Charter operator is an indirect air carrier authorized to engage in the formation of groups for transportation on Public Charters (the regulation defines a U.S. Public Charter operator and a foreign one separately). An indirect air carrier holds out and sells transportation to the public but does not itself operate the aircraft — it contracts that flying to a direct air carrier. The public charter operator's obligations are economic and consumer-protection in nature: filing the prospectus/charter agreement with DOT where required, complying with the Part 380 rules on advertising and the handling of passenger funds (escrow/surety), and meeting DOT registration requirements. The FAA safety obligations sit with the direct air carrier that flies the trip.
Is a public charter safe? Who is responsible for safety?
On a properly structured public charter, the flying is done by a certificated direct air carrier — most commonly a Part 135 on-demand operator, and in some cases a Part 121 carrier — and that certificate holder is responsible for the FAA safety standard: airworthy aircraft, qualified and current crew, an approved maintenance program, operational control, and the required records. The Part 380 operator handles the economic/consumer side, not the cockpit. That said, the FAA has publicly stated that some scheduled-service-style public charters have grown so large in volume, scope, and frequency that they can resemble Part 121 airline operations while being flown under Part 135 rules, and it has signaled rulemaking to address that gap. This is an evolving, fact-specific policy area — for any specific operation, consult a qualified aviation attorney.
Is the Part 380 public charter a loophole that lets airline-like service avoid Part 121?
"Loophole" is the popular framing, but the precise picture is narrower. Part 380 is a legitimate, long-standing DOT economic structure, and public charters are flown by certificated FAA operators. The concern the FAA has raised is structural: a charter operator can sell individual seats on frequent, published-schedule, point-to-point flights that look to a passenger like an airline, while the flying is conducted under Part 135 rather than the more stringent Part 121 standard that would otherwise apply to comparable scheduled service. On August 24, 2023 the FAA announced a Notice of Intent to consider revising the regulatory definitions of "on-demand," "supplemental," and "scheduled" operations, and on September 22, 2025 DOT and FAA described further long-term actions, including potentially removing references to public charters and Part 380 from those definitions. Whether and how the rules change — and whether a given operation is affected — is exactly the fact-specific legal question to put to an aviation attorney.
Why is the FAA and DOT scrutinizing public charters right now?
The driver is the rapid growth of scheduled-service-style public charters. In its August 24, 2023 Notice of Intent, the FAA explained that over roughly the prior decade public charters had been offered in such volume, scope, frequency, and complexity that some were difficult to distinguish from Part 121 air carrier operations, and that the safety regulations that would otherwise govern the flights should apply, up to Part 121. DOT and FAA have since (September 22, 2025) outlined near-term and long-term steps, including potential changes to the on-demand/supplemental/scheduled definitions and to how Part 380 is referenced. An FAA Associate Administrator publicly indicated that if changes are made there would be a window of at least three years before implementation. This is proposed/evolving policy, not a settled rule — verify the current status and consult counsel before relying on any structure.
Who has to keep the compliance records on a public charter — the operator or the carrier?
Both, for different things. The direct air carrier flying the trip keeps the FAA operating records its certificate requires — airman and medical certificates, training/checking and currency records, duty and flight-time records, aircraft airworthiness and maintenance records, AD compliance, weight-and-balance, and operational-control/flight-release paperwork. The Part 380 public charter operator keeps the DOT economic and consumer-protection records — the filed charter agreement/prospectus where required, advertising substantiation, and documentation of the depository/escrow handling of passenger funds. When the FAA or DOT comes asking, each party has to produce a complete, dated, retrievable record set for its side. FileFlo is built to keep the operator's document set current, complete, and instantly retrievable; it does not represent you to the FAA or DOT, file appeals, or give legal advice.
How is a public charter different from a direct Part 135 charter and from a Part 121 airline?
A direct Part 135 charter is the simple case: the customer contracts the certificated operator directly, and that operator both sells and flies the trip under Part 135 on-demand rules. A public charter adds a layer: a Part 380 charter operator (an indirect air carrier) forms the group and sells the seats, and a direct air carrier flies the trip — so the booking entity and the operating entity are different. A Part 121 airline is a scheduled (or supplemental) air carrier that both holds out and operates under the more stringent Part 121 standard. The current policy debate is essentially about where high-frequency, schedule-like public charters belong on that spectrum. For the underlying operating-rule differences, see our guide on Part 91 vs Part 121 vs Part 135.
