The Short Answer

Skiplagging — also called hidden city ticketing, point beyond ticketing, or throwaway ticketing — is not illegal under U.S. federal law. There is no criminal statute against buying an airline ticket and choosing not to fly every segment of it. The Department of Transportation, which regulates airline consumer practices, has not prohibited the practice.

What skiplagging is: a breach of the airline's contract of carriage. This is the private contract you agree to whenever you buy a ticket. Every major U.S. airline — American, Delta, United, Southwest, Alaska, JetBlue — includes language in their contracts of carriage explicitly prohibiting hidden city ticketing.

The distinction is critical. A criminal violation could lead to arrest, prosecution, and a criminal record. A contract violation gives the airline civil remedies — the right to penalize you within the bounds of what the contract allows, but nothing more.

In plain English: Airlines cannot have you arrested or charged with a crime for skiplagging. They can cancel your ticket, void your miles, ban you from future bookings, and in rare cases pursue civil damages.

What the Law Actually Says

To understand why skiplagging exists in a legal gray zone, you have to understand the two layers at play: federal law and private contract law.

Federal law: The U.S. Department of Transportation (DOT) regulates airline consumer protections — things like baggage fees, refund policies, tarmac delay rules, and disability accommodations. The DOT has not promulgated any rule that prohibits passengers from skipping segments of their booked itinerary. There is no statute, no regulation, no enforcement mechanism at the federal level targeting individual skiplaggers.

Contract law: Every airline ticket is a contract. By purchasing the ticket, you agree to the airline's contract of carriage — a lengthy document spelling out the rules of the booking. United's Rule 6, for example, addresses "Improper Ticketing Practices" and states that tickets "may not be purchased and used to bypass fare construction rules or to defeat the application of any fare, such as to use hidden city or back-to-back ticketing." American's contract requires tickets to be used "in sequence from the origin to destination." Delta and Southwest include similar provisions.

When you skiplag, you breach this contract. The airline's remedies for that breach are limited to what the contract itself permits — they cannot invent new penalties beyond what they've already disclosed to you.

The May 2025 Ruling: What It Actually Means

The legal landscape around skiplagging changed meaningfully in May 2025, when a federal court in Texas issued the final ruling in American Airlines v. Skiplagged.

Here's what happened. In August 2023, American Airlines sued Skiplagged.com — the booking platform that specializes in hidden city fares — claiming the site was infringing American's trademarks, violating its terms of service, and tortiously interfering with the airline's business. American sought more than $94 million in damages.

After a five-day trial in October 2024, a federal jury in Fort Worth ruled mostly in American's favor on one narrow issue: copyright. Skiplagged was using American's logos and copyrighted fare data on its website without authorization. The jury awarded American $9.4 million in copyright damages.

But on the more important issues — whether Skiplagged could facilitate hidden city bookings at all, and whether the underlying practice was lawful — Skiplagged won. The jury rejected American's trademark infringement claim entirely. The court declined to find that Skiplagged's business model was unlawful. The May 2025 final ruling confirmed that skiplagging itself remains legal.

In the words of Skiplagged CEO Aktarer Zaman: "American lost on three of its four claims, and Skiplagged remains free to continue its business of showing consumers all flights to help them save money."

What this means in practice

A Brief Legal History

Airlines have been trying to stop skiplagging through lawsuits for over a decade. Here's how it's gone:

2014: United Airlines + Orbitz v. Skiplagged. Filed in federal court in Chicago. United and Orbitz sought $75,000, claiming "unfair competition." In 2015, a federal judge dismissed the case for lack of jurisdiction — Skiplagged founder Aktarer Zaman didn't live or do business in Illinois. Orbitz separately settled with Skiplagged; United's claims went nowhere.

2018: Lufthansa v. Individual Passenger. Filed in Berlin, Germany. Lufthansa sued a passenger who had skiplagged on a Frankfurt-Oslo itinerary, demanding €2,112 in fare differential. A Frankfurt court initially dismissed the case. Lufthansa appealed, and the case remains on appeal. Notably, the court agreed Lufthansa's basis for suing was valid — the case was dismissed on technical issues with the airline's price calculation, not on the legality of skiplagging itself.

2021: Southwest Airlines v. Skiplagged. Filed against Skiplagged.com. Settled out of court in 2023 with no public terms.

2023-2025: American Airlines v. Skiplagged. The big one. Filed August 2023, jury verdict October 2024, final ruling May 2025. American won $9.4 million on copyright but lost on trademark, contract, and tortious interference claims. Both sides are appealing. Skiplagged continues to operate.

The pattern across all four lawsuits: No court has ever held that the underlying act of skiplagging is illegal. Airlines have won partial victories on tangential issues (copyright, logo use) but consistently lose when they try to argue the booking practice itself is unlawful.

What Airlines Can Actually Do to You

Just because skiplagging is legal doesn't mean it's consequence-free. Airlines have substantial contractual tools to penalize travelers they catch. Here's the realistic range of what can happen.

Cancel your remaining itinerary

This is the most common penalty and the easiest one to trigger. The moment you no-show for any segment of a booked itinerary, the airline's automated system cancels every remaining segment. Booked a round-trip and skiplagged on the outbound? Your return flight home is cancelled, automatically, before your trip even ends. This is why skiplagging only works on one-way tickets or two separate one-ways booked individually.

Void your frequent flyer miles

If you booked your hidden city ticket with your loyalty number attached, the airline can revoke any miles earned on that booking — and in cases of repeated violations, terminate your account entirely and forfeit all accumulated miles. The Points Guy and other travel publications regularly document cases where flyers with hundreds of thousands of miles lost everything after airlines detected skiplagging patterns.

Revoke elite status

Gold, Platinum, Diamond, Executive Platinum — all can be stripped. Years of mileage-running and the perks that come with status disappear in a single enforcement action.

Ban you from future bookings

Airlines maintain internal "do not fly" lists for passengers who repeatedly violate contracts of carriage. In one widely-reported 2023 case, American Airlines pulled a teenager off a flight at Gainesville Regional Airport in Florida, banned him for three years, and forced his family to buy a new ticket — all because he had skiplagged a connection.

Charge you the fare differential

Some airlines now proactively charge the difference between your skiplagged fare and what a direct ticket to your actual destination would have cost. This is permitted under most carriers' contracts of carriage. American's contract is particularly explicit on this point.

Sue you personally

Rare but not unprecedented. Lufthansa is the only major airline to actually pursue an individual passenger through litigation, and that case has dragged on for years without a final judgment. American Airlines targeted the booking platform, not individuals. For an occasional skiplagger, the risk of personal litigation is near zero. For someone doing it systematically with status accounts attached, the risk rises significantly.

How Airlines Detect Skiplagging

Understanding detection helps you understand risk. Airlines use multiple methods to identify skiplaggers, and they've gotten more sophisticated each year.

Pattern detection in booking history. Airlines flag passengers whose itineraries repeatedly show the same routing pattern — book a connecting flight, no-show for the final segment. If you've done this two or three times on the same airline, you're likely already on their watch list.

Gate agent observation. Gate agents can see your full itinerary at check-in. If you're carrying only a backpack on a flight to a long-haul destination that would obviously require checked luggage (Phoenix to London on a 10-day trip), they may question you. Gate agents have been known to ask passengers about hotel reservations at the final destination as a way of testing whether they plan to actually go there.

Loyalty account analysis. Once a frequent flyer number is on a booking, the airline can correlate your booking history across years. Even a single skiplagged ticket connected to your account creates a permanent record.

Geolocation data. Some airlines now use mobile app and Wi-Fi data to determine where passengers actually deplane versus where their ticket says they're going. This is newer and not universal, but it's becoming more common.

Tips from staff. Flight attendants, customer service agents, and even fellow passengers can flag suspected skiplaggers. Skiplagged itself warns users not to joke about the practice within earshot of airline staff.

The countermeasure: don't give them detection signals. Book without a loyalty number. Don't fly the same skiplag route twice on the same airline. Travel like a normal passenger to the layover city — same boarding behavior, same arrival behavior, no obvious tells.

The International Picture

U.S. law is clear that skiplagging is legal. But international law gets more complicated, and the answer varies by jurisdiction.

European Union: German courts have heard the only major skiplagging lawsuits in Europe (the Lufthansa cases). The current precedent leans in favor of passengers, but the law is unsettled. The Lufthansa appeal is ongoing. Spanish courts have reached similar conclusions in cases involving Iberia.

United Kingdom: No prominent legal cases. The practice is not criminalized.

Canada, Australia, New Zealand: No criminal prohibition. Airlines enforce through their contracts of carriage similarly to the U.S.

The added wrinkle: international hidden city ticketing introduces visa and customs issues that don't exist domestically. If your ticketed destination is a country you'd need a visa to enter, the airline may demand proof of that visa at check-in — even though you have no intention of actually going there. This adds friction that often makes international skiplagging not worth the complication.

For most travelers, the practical takeaway is: skiplagging works best within the United States, where the legal status is clearest and the documentation requirements are minimal.

What You Cannot Get Sued For

Some clarifications on what airlines cannot do to you, even if they catch you skiplagging:

What they can do is everything in the previous section. Know the difference.

Should You Skiplag?

This is the question the legal status doesn't answer for you. Legal does not mean wise for your specific situation. Some honest considerations:

Skiplagging makes sense when: you have a one-time need to save significant money (savings exceeding $150-200), the route is right (hub city destination, single-airline-dominated direct fare, competitive connecting fare), you're flying carry-on only, you don't have elite status on the airline, and you accept the risk of cancelled return tickets or other consequences.

Skiplagging doesn't make sense when: you fly a particular airline frequently and care about loyalty status, you need checked luggage, you have specific time-sensitive plans that can't accommodate a cancelled return, your savings would be less than $100-150 (the risk-reward math doesn't work), or you're not comfortable with the contract-violation aspect on ethical grounds.

The legality question is settled. The practical question — "is this worth it for my trip?" — depends on factors only you can weigh. Our complete guide to hidden city flights covers when the strategy actually saves money and when it doesn't.

How FareFinderAI Approaches This

We built FareFinderAI to give travelers the full menu of ways to save on flights — including hidden city options when they make sense, and not including them when they don't. Our AI evaluates every route across legitimate strategies (direct fares, open-jaw routings, positioning flights, cashback opportunities) plus hidden city fares where applicable.

When a hidden city fare is the best option for your trip, we surface it clearly with the relevant rules and risk warnings. When a legitimate option saves you nearly as much without the contract-of-carriage complications, we show you that instead.

Our goal isn't to push every traveler into skiplagging. It's to make sure you know all your options, with honest legal context, so you can make the call that fits your situation.

Frequently Asked Questions

Can I go to jail for skiplagging?
No. Skiplagging is not a crime. There is no federal or state law prohibiting it. The worst legal consequence would be a civil lawsuit by the airline, which is rare and would result only in financial penalties, not imprisonment.
Will skiplagging affect my credit score?
No. Contract of carriage violations don't appear on credit reports. The only way skiplagging could affect your credit is if an airline successfully sued you in civil court for fare differential and the judgment went unpaid — at which point it could appear as a collections item. This scenario has happened essentially never in the United States.
Can the TSA stop me from skiplagging?
No. The TSA's role is security screening. They don't enforce airline contracts of carriage. They have no jurisdiction over whether you complete every leg of your booked itinerary.
Is skiplagging fraud?
No. Fraud requires misrepresentation that induces reliance. When you buy an airline ticket, you're not promising to fly every segment — you're promising to pay for every segment, which you've done. The legal consensus across courts is that not using every leg of a paid ticket is not fraud.
What if I have elite status — is it worth the risk?
Almost certainly not. Elite status is one of the highest-value assets airlines award, and they protect it carefully. A single detected skiplag against your loyalty account can cost you tens of thousands of dollars in benefits. If you have status, find another way to save.
Can my employer find out if I skiplag a business trip?
Only if the airline complains to your employer directly, which is exceptionally rare. However, if you booked the trip on a corporate card or through a corporate travel agent, the airline's contract enforcement might create a paper trail that surfaces in expense reporting. Not recommended for corporate travel.
Is hidden city ticketing legal internationally?
The legal status varies by country. In the U.S., it is legal. In the EU, current precedent (especially in Germany and Spain) generally favors passengers but is unsettled and on appeal. Most other developed countries follow similar contract-law principles. There is no country where skiplagging is criminally prohibited.
What's the appeal status of the American Airlines case?
As of May 2026, both sides are appealing portions of the verdict. American Airlines is appealing the trademark loss. Skiplagged is appealing the $9.4 million copyright judgment. Neither appeal challenges the core finding that skiplagging itself is legal. Resolution is expected sometime in 2027 or beyond.

The Bottom Line

Skiplagging is legal in the United States. It violates airline contracts but does not violate any law. The May 2025 court ruling confirmed that the practice itself is lawful, even as it imposed copyright damages on Skiplagged.com for using airline branding. Airlines can penalize you with cancelled tickets, lost miles, and bans — but they cannot criminally prosecute you or have you arrested.

For travelers who follow the rules (carry-on only, one-way tickets, no loyalty number, occasional use), skiplagging remains a viable way to save 40-60% on the right routes. For travelers with elite status or who fly the same airline frequently, the risk-reward math doesn't work.

The law is on your side. The airlines are not. Plan accordingly.
