How we know: Sources are listed at the end. This post describes a method; it deliberately avoids quoting fare savings because they depend on your origin, the gateway and the date. Check live prices on the route pages.
A positioning flight is a short flight you buy separately to reach an airport where the long-haul fare is cheaper. It exists because long-haul fares are set by competition at the gateway, not by distance from your house: a resident of Buffalo, Richmond or Columbus may find that Boston, New York or Chicago to Europe is priced far below their home airport to the same city, even after adding a cheap domestic hop.
When positioning makes sense
- Your home airport has little long-haul competition and a big gateway with several transatlantic carriers (New York, Boston, Chicago, Washington, Miami, Los Angeles, San Francisco) is a short, cheap flight or train ride away.
- The gateway fare is markedly lower, not marginally. Positioning adds cost, time and risk; it needs a real gap to be worth it.
- You can build in buffer, ideally an overnight at the gateway, or at least several hours.
- You are travelling light, so a separate ticket does not mean re-checking bags under time pressure.
When it does not
- The gap is small once you add the positioning fare, a night's hotel if needed, and ground transport.
- Your trip is short; a day lost each way to positioning is a big share of it.
- You are travelling with family or a lot of luggage.
- A through-ticket from home on the same alliance is only slightly more and comes with connection protection.
The math, honestly
Write down four numbers: the through-fare from home; the gateway's long-haul fare; the positioning fare each way (including bags); and any hotel or ground cost. Positioning wins when the second, third and fourth together are comfortably below the first, with enough margin to cover the risk of a missed connection. If the margin is thin, take the through-ticket.
How to find the gateway fare
Google Flights' "Airports" insight shows fares from alternative nearby airports for your search (Google Flights Help); for farther gateways, search them directly. Compare the same dates from your home airport and from the gateways. Route pages show the current price on the main gateways, for example Boston to London, JFK to London, Chicago to London and Boston to Lisbon.
How to book it without getting burned
- Book the long-haul first, then the positioning flight. The long-haul is the scarce, expensive part.
- Use the 24-hour rule. Tickets bought directly with a US airline at least seven days out can be cancelled within 24 hours for a full refund (Thrifty Traveler). Book the long-haul, confirm the positioning flight exists at a sensible time and price, and if not, cancel within the day.
- Separate tickets are separate contracts. If the positioning flight is late and you miss the long-haul, the long-haul carrier owes you nothing. Take the first flight of the day, or arrive the night before.
- Consider the train for Boston–New York–Washington positioning; it is less weather-sensitive and drops you downtown.
- Check the return too. Positioning back home after an overnight flight is where plans fail; allow real time.
Combining positioning with low-cost carriers
Long-haul low-cost airlines (see our budget airlines to Europe guide) fly from a handful of US gateways. Positioning is how travellers outside those cities use them. Remember that their fares exclude bags and seat selection; add those before you compare.
FAQ
What is a positioning flight? A separately booked short flight to the airport where your main long-haul fare departs.
Is it worth it? Only with a clear gap after all costs and a time buffer you are comfortable with. Otherwise book the through-fare.
Can I position on points? Yes, and short domestic awards are one of the better uses of a small balance.
