You are looking at two prices for what is almost the same flight. Copenhagen to Frankfurt is €210. Copenhagen to Frankfurt to Milan is €140, and it stops in Frankfurt for two hours. If Frankfurt was where you wanted to go anyway, the cheaper ticket is the one that carries you past it. Walk out of the airport at the layover, skip the last leg, and you have paid €70 less to reach the same city.
That is the whole idea behind getting cheap flights by getting off at the layover. It has a name in the industry — hidden-city ticketing, or skiplagging — and it works often enough that a whole website was built around finding those fares. It also carries real costs that the €70 saving hides. Here is how the pricing quirk happens, when it is worth using, and what airlines actually do when they notice.
Why the longer flight is sometimes cheaper
Airfare is not priced by distance. It is priced by what a route can bear. On a city pair where one airline dominates and business travelers have no alternative, fares stay high. On a route where three carriers compete for connecting traffic, fares drop, even when the cheaper itinerary flies further and burns more fuel.
Hub cities take the worst of this. Frankfurt, Amsterdam, Atlanta, Dallas, Charlotte — if a single airline runs most of the departures, direct flights into that hub often cost more than flights that merely pass through it on the way somewhere less contested. The airline is not making a mistake. It is charging the direct passenger more because it can, and discounting the connecting passenger to win them from a competitor.
Skiplagging is what happens when a traveler buys the discounted connecting fare and simply stops at the hub. Same seat, same flight, less money. The airline loses the premium it had counted on.
Where these fares turn up most
Routes into a dominant carrier’s hub are the usual hunting ground. So are one-way domestic tickets in large countries, and short European hops out of an airport where a legacy airline has little competition. If you already read our guide to finding the cheapest airfares, this belongs in the same toolbox as flexible dates and nearby-airport searches. It is just the most rule-breaking tool in the box.
Is it legal, and is it allowed?
Those are two different questions, and mixing them up is how people get burned.
Legal: in the United States, yes. No federal law says you must board every segment of a ticket you paid for. A federal jury in Texas found the practice itself lawful, and the fare-finding site at the center of the case is still running. TravelPulse covered that ruling in detail.
Allowed: no. Airlines prohibit it in their own contract with you. United’s conditions of carriage name “hidden city” ticketing outright as an improper ticketing practice, and American, Lufthansa and others carry similar language. Legal but forbidden means the state will not come after you, and the airline still can — by enforcing the contract you agreed to when you clicked buy. The Points Guy keeps a running rundown of what each carrier’s rules say.
Lufthansa has taken a passenger to court in Germany over a skipped leg. A teenager flying American was stopped at the gate in Florida, had his ticket cancelled and was made to buy a new one. Neither of those was a criminal matter. Both cost the traveler more than the fare they were trying to beat.
The four rules that make it work at all
Get any one of these wrong and the saving evaporates.
Carry-on only. Checked bags are tagged to the final destination on the ticket. Yours would fly on to Milan while you stand in Frankfurt. There is no way to retrieve it at the connection and no sympathy at the desk when you explain why you want it.
One-way tickets only. When you skip a segment, the airline cancels everything after it, automatically. Skip the outbound’s second leg on a round trip and your return home is gone. This is the mistake that turns a €70 saving into a €400 last-minute replacement fare.
Leave your frequent flyer number out. Entering it hands the airline a clean link between the pattern and your account. Miles can be stripped and elite status can be pulled. Whatever the miles on one cheap hop were worth, they are worth less than the balance you would lose.
Do it rarely. Carriers moved to automated detection, and repetition is exactly what an algorithm is good at spotting. One skipped leg in a year reads as a missed connection. Six reads as a habit.
What you save against what you risk
| Factor | Normal ticket | Skiplagged ticket |
|---|---|---|
| Typical saving | None | Roughly 20–40% on the right route, occasionally more |
| Checked luggage | Fine | Not possible |
| Return leg | Protected | Cancelled if you skip an earlier segment |
| If the airline reroutes you | They owe you your destination | A new routing may skip your real stop entirely |
| Loyalty account | Earns normally | Miles and status can be removed |
| Worst case | Delay | Ticket voided at the gate, replacement bought at walk-up price |
Percentage ranges here are typical of what travelers report on hub routes, not a guaranteed discount. Some searches turn up nothing. Read them as a rough shape rather than a promise.
The reroute problem nobody plans for
This is the failure mode that catches careful people. Your itinerary says Copenhagen to Frankfurt to Milan and you intend to stop in Frankfurt. Weather closes Frankfurt for the afternoon. The airline rebooks you helpfully and efficiently: Copenhagen to Munich to Milan. You are now holding a valid ticket to a city you never wanted, and Frankfurt is not on it.
On a normal ticket that reroute is a service. On a hidden-city ticket it destroys the entire point of the booking, and you cannot object without revealing the plan. Never skiplag toward something you cannot miss — a wedding, a cruise departure, a job interview, the first night of a hotel you already paid for.
The honest alternatives
Most of the time there is a duller way to get most of the same saving without gambling on the fare rules.
Fly the layover on purpose. Many airlines sell multi-day stopovers on connecting itineraries, sometimes for nothing extra. You get the hub city legitimately, with your luggage, and the rest of your ticket intact. We wrote about why a long layover is often worth choosing rather than avoiding.
Check the nearby airport. A train from the next city over frequently beats the skiplagged fare and breaks no rules. Milan, Brussels and Frankfurt all have secondary airports within an hour of the center.
Move the dates. Tuesday and Wednesday departures, and anything outside school holidays, usually undercut the weekend price by more than a hidden-city trick would save.
Spend the difference on the ground instead. Shaving €70 off a fare matters less than what you pay for six nights of beds. Our notes on getting cheap accommodation and the wider set of practical travel tips tend to move the total more than the flight does.
So should you do it?
Once, on a one-way, with a cabin bag, to a city you would shrug about missing, without your loyalty number attached — the odds are strongly in your favor and the saving is real. That is a narrow set of conditions, and it is narrower than the people posting about it online usually admit.
Repeatedly, on round trips, with checked bags, toward something time-critical, on the one airline you hold status with: the arithmetic turns against you fast. One voided ticket at a gate in July costs more than a year of small savings.
Build the trip around the flight you actually book
Whichever ticket wins, the awkward part comes next. A cheap fare that lands at 23:40 in a hub you did not plan for needs a bed near the airport, a train time you have checked, and a first day that survives a short night. That is what Lentii is for: put the flight, the beds and the day-by-day plan in one place, share it with whoever is coming, and see immediately where the schedule does not hold. Start your itinerary and let the cheap flight be the beginning of the plan instead of a loose end.
FAQ
Can you really get cheap flights by getting off at the layover?
Yes, on the right route. A connecting fare through a busy hub is sometimes 20–40% cheaper than the direct flight into that same hub, and getting off at the connection costs you nothing extra. It only works with carry-on luggage, on one-way tickets, and it breaks the airline’s own conditions of carriage even though no law forbids it.
What happens if the airline catches you skiplagging?
Nothing criminal. Airlines enforce it as a contract matter: your remaining segments can be cancelled, frequent flyer miles removed, elite status revoked, and in rare cases you are stopped at the gate and told to buy a new ticket at walk-up price. Enforcement has become more automated, so a pattern of skipped legs is far riskier than a single one.
Can you check a bag on a hidden-city ticket?
No. Bags are tagged through to the ticket’s final destination, so your luggage flies on without you. Anything you cannot fit in a cabin bag stays home, and that alone rules the trick out for most longer trips.
