Why this page exists

Almost every article about skiplagging says the same thing: "it violates the airline's contract of carriage." Almost none of them tell you which clause, what it actually says, or what the airline can specifically do to you.

So we went and read them. Below is the verbatim language from each carrier's current contract of carriage, the rule number, and the exact list of remedies each airline reserves for itself. Every clause was pulled from the airline's own published contract, not from secondary reporting. Sources and verification dates are at the bottom.

The policies, side by side

Airline Where it lives What the contract says What they reserve the right to do Stance
American Conditions of Carriage →
Ticket validity →
Prohibited booking practices
Lists first among prohibited practices: "Purchasing a ticket without intending to fly all flights to gain lower fares (hidden city ticketing)" Cancel any unused part of the ticket · refuse to let you fly and check bags · not refund an otherwise refundable ticket · charge you what the ticket would have cost · claw back any compensation already paid to you. Separately, American will reject a baggage claim from anyone who "used a prohibited booking practice and then made a claim." Explicit ban
Delta Contract of Carriage (Domestic) →
Rule 16(C)
Defines it directly: "Hidden City/Point Beyond Ticketing - The purchase or usage of a fare from a point before the passenger's actual origin or to a point beyond the passenger's actual destination." Cancel any unused portion · void any remaining value of the ticket · refuse to let you board or check bags · charge you the "Applicable Full Fare" if you are permitted to board. Explicit ban
United Contract of Carriage →
Rule 6, Prohibited Practices
Names and defines it: tickets may not be bought and used at fares "to a more distant point(s) than the Passenger's actual destination being traveled even when the purchase and use of such Tickets would produce a lower fare. This practice is known as 'Hidden Cities Ticketing' or 'Point Beyond Ticketing' and is prohibited by UA." United also reserves a catch-all for "Any practice that United believes, in its sole discretion, is exploitative." Without notice to the passenger, and at its "sole discretion": invalidate the ticket · cancel the rest of your itinerary · confiscate unused flight coupons · permanently ban you or refuse to carry you and your bags unless you pay the fare difference at the gate · assess you any amounts owed, including for "seat blocking." Explicit ban, harshest
Southwest Contract of Carriage →
§ 2.a.(2)(vi),
Prohibited Booking Practices
Lists it first, in language nearly identical to American's: "Purchasing a Ticket without intending to fly all flights to gain lower fares (hidden cities)" Without advance notice: cancel any unused part of the ticket · cancel other reservations it believes were made without intent to travel · refuse to fly you and your checked bags · not refund an otherwise refundable ticket · charge you what the ticket would have cost · claw back compensation already paid. Explicit ban
Alaska Contract of Carriage →
Rule 7
Prohibits throwaway, back-to-back, and "Hidden Cities Ticketing" or "Beyond Point Ticketing": buying a fare to a point more distant than where you actually intend to travel. Cancel the remaining itinerary · confiscate unused flight coupons · refuse to board you or carry your bags unless the fare difference is collected first · refuse to refund an otherwise refundable ticket · assess you the actual remaining value of the ticket. Explicit ban
JetBlue Contract of Carriage No hidden-city clause. JetBlue's contract does not use the term. It relies on general routing language: fares "apply only between the points named and via the routing as shown in carrier's current schedule and are not applicable to or from intermediate points." No hidden-city-specific remedies are spelled out. JetBlue retains general rights to cancel tickets and refuse carriage, but the contract does not name the practice or attach penalties to it. No explicit clause
Spirit · Frontier n/a Not verified. We could not confirm explicit hidden-city language in either carrier's published contract of carriage as of July 2026. Both have declined to comment publicly on their enforcement posture. We would rather leave a gap here than guess. Unknown. Treat as unresolved, not as permission. Unverified

What the airlines can actually do to you

Read all five explicit bans together and a consistent set of remedies emerges. Airlines reserve the right to:

  • Cancel the rest of your ticket. Universal. Every carrier with a clause claims this, and it is the one they actually use. Skiplag the outbound of a round trip and the return can simply vanish.
  • Refuse to board you, and your bags. Also universal. Note that this is about checked baggage: your bag is tagged to the ticketed final destination, which is why hidden-city travel is carry-on only.
  • Bill you the fare difference. American, Delta, Southwest, United and Alaska all reserve this. In practice it shows up as a demand letter or an account-level charge rather than a lawsuit.
  • Void a refundable ticket. You paid extra for refundability; violate the clause and American, Southwest and Alaska all say that protection evaporates.
  • Ban you. United is explicit about a permanent ban. Others reserve the general right to refuse transport.
  • Take your miles. Not in the contracts of carriage themselves but in the loyalty program terms, which is why frequent flyers with status have far more to lose than one-off travelers.

The one that catches people out: American's baggage-liability section says it may reject your claim if you "used a prohibited booking practice and then made a claim." So if you skiplag and the airline loses the bag you did check on a legitimate segment, they have written themselves a reason to deny you.

Prohibited is not illegal. This is the whole point.

A contract of carriage is a private agreement between you and an airline. Breaching it exposes you to the remedies in that contract, and to nothing else. It is not a statute. Breaking it is not a crime. No U.S. court has ever ruled that a passenger who skiplagged their own paid ticket broke the law.

The case record bears this out, and it is short:

  • United & Orbitz v. Zaman (2014-2015). United and Orbitz sued Skiplagged's founder, Aktarer Zaman, in Chicago. The case was dismissed in 2015 on jurisdictional grounds: Zaman neither lived nor did business there. Orbitz settled separately. The court never reached the question of whether skiplagging is lawful, and United did not refile.
  • Lufthansa v. passenger (Germany, 2018-2019). Lufthansa sued a traveler who skipped the last leg of a booking, seeking the fare difference. A Berlin court dismissed the claim in December 2018. Lufthansa appealed, the district court signalled deep skepticism that an airline can charge a consumer for a service already paid for and simply not consumed, and on October 2, 2019 Lufthansa withdrew the appeal without explanation.
  • American Airlines v. Skiplagged (N.D. Tex., 4:23-cv-00860). The big one, and the most misreported. On October 15, 2024 a Fort Worth jury awarded American $9.4 million: $4.7M in copyright damages and $4.7M in disgorgement of Skiplagged's revenue. The court entered final judgment in May 2025 with a permanent injunction barring Skiplagged from displaying American's copyrighted material.

What that $9.4 million was actually for: copyright. Skiplagged used American's logo and imagery without a licence. The jury found American's trademark claim amounted to nominative fair use and awarded zero trademark damages. Nothing in the verdict held that hidden city ticketing is unlawful, and no passenger was a defendant. American appealed the fair-use finding to the Fifth Circuit on June 9, 2025 (No. 25-10703); Skiplagged cross-appealed the copyright damages on June 23. Briefing is ongoing.

Southwest also sued Skiplagged and settled out of court, with no public terms.

So the score, after a decade of litigation: airlines have won a copyright judgment against a website. They have never won a case against a passenger for the practice itself. Every attempt has been dismissed, withdrawn, or settled.

What this means if you're actually considering it

The asymmetry is the thing to understand. You are not risking prosecution. You are risking your relationship with an airline, and the size of that risk depends entirely on how much that relationship is worth to you.

  • If you have elite status or a big mileage balance: the airlines' most usable weapon is the one aimed straight at you. The math rarely works.
  • If you fly a carrier once a year: the realistic downside is a cancelled return leg and a demand letter you are unlikely to receive.
  • Carry-on only. Always. A checked bag goes to the ticketed destination. There is no version of this where checked bags work.
  • One-way tickets only. Skip a leg on a round trip and the rest of the itinerary can be cancelled under every contract above.
  • Don't put your frequent flyer number on it. It is how the pattern gets detected across bookings.

Sources and method

Every clause above was read directly from the carrier's own published contract of carriage in July 2026, not from secondary reporting. Contracts change (American's was last updated May 12, 2026 and Alaska's May 26, 2026), so verify before you rely on any of this.

Frequently Asked Questions

Which airline is strictest about hidden city ticketing?

United. It is the only major U.S. carrier whose contract reserves the right to invalidate your ticket without notice, permanently ban you, and assess charges including for "seat blocking", and it grants itself a catch-all over any practice it considers "exploitative" in its sole discretion.

Does any major U.S. airline allow hidden city ticketing?

None permit it outright. JetBlue is the only major carrier with no explicit hidden-city clause in its contract of carriage, relying instead on general routing language. That is an absence of a specific prohibition, not permission.

Can an airline actually make me pay the fare difference?

They reserve the right to, and American, Delta, United, Southwest and Alaska all say so in writing. In practice it usually arrives as a demand letter or a charge against your loyalty account rather than a lawsuit, because suing a passenger is expensive, and airlines have not won such a case.

Has any passenger ever been sued for skiplagging and lost?

Not in the United States. Lufthansa tried in Germany, lost at first instance, and withdrew its appeal in 2019. Airlines have sued websites successfully, on copyright grounds, but never a passenger, successfully, over the practice itself.

Did the American Airlines v. Skiplagged verdict make skiplagging illegal?

No. The $9.4 million was awarded for copyright infringement over Skiplagged's use of American's logos and imagery. The jury found the trademark use was nominative fair use and awarded nothing on it. The legality of the booking practice was not decided, and no passenger was a party to the case.
