When you have two flights to reach a single destination, it is most commonly called a "connecting flight" or a "layover." The individual segments of the journey are referred to as "legs" or "sectors." For example, if you fly from New York to London with a stop in Reykjavik, the stop in Iceland is your layover, and the two separate flights are your connecting flights. If you are specifically booking a trip that visits multiple cities with a long break in between (more than 24 hours), it is called a "multi-city flight" or a "stopover." In airline industry terms, this is often called an "indirect" itinerary. There is also a distinction between a "connection" and a "transfer"; a connection usually implies you are staying with the same airline or its partners on one ticket, while a "self-transfer" means you have booked two separate tickets and are responsible for moving your own luggage between the flights. In 2026, many travel apps use the term "1-stop" to denote an itinerary with two flights, allowing travelers to quickly differentiate between a "non-stop" journey and one that requires changing planes at an intermediate hub.
