A connecting flight is a journey that requires you to change planes at an intermediate airport (a "layover" or "transfer" point) before reaching your final destination. Unlike a "direct" or "non-stop" flight which uses a single aircraft, a connecting flight involves at least two different flight numbers and two separate takeoffs and landings. For example, if you fly from London to New York with a stop in Dublin, you are on a connecting flight. There are two types: online connections, where you stay with the same airline or its partners (and your bags are usually checked through to the end), and interline/self-transfers, where you book separate tickets on different airlines and may need to collect and re-check your bags. A "legal" connection is one that meets the airport's "Minimum Connection Time" (MCT), ensuring you have enough time to navigate security or customs. If your first flight is delayed and you miss your connection on a single-ticket booking, the airline is generally responsible for rebooking you on the next available flight.
