Connecting flight

A connecting or transit flight requires passengers to switch planes at an intermediate airport before reaching their final destination. This is usually necessary when there are no direct flights between the departure and arrival cities.

Some travelers choose connecting flights to save on costs, as they are often less expensive than direct flights, or to have a layover in another city for a brief exploration. 

For example, if you are traveling from Los Angeles (LAX) to Athens (ATH) with British Airways, you might first fly to London Heathrow (LHR). After a layover in London, you would board a connecting flight to Athens. 

Connecting flights can involve multiple carriers through interline or codeshare agreements. It means that different airlines work together, and one can sell tickets for a flight operated by another carrier. These partnerships allow passengers to easily travel with different airlines, check in only once, and have their baggage transferred seamlessly between flights.
