If the missed connection is the airline’s fault (a delayed initial flight due to mechanical problems, for example), the airline should rebook you on the next available flight.
If the next outbound flight is the following morning, the airline should either book you on another airline or provide accommodations and meals.
Do connecting flights wait delayed passengers?
Not usually because it cause passengers on that plane to miss their connections, as well as making the flight late. If you’ve booked both flights on the one ticket then the airline will put on the next flight with available seats. You can safely say that airlines will not wait for connecting passengers.
Can I get compensation for missed connection?
What are you entitled to under EC 261 if you miss your connection? If you missed your flight connection because of a delay, you are entitled to missed connection compensation of up to €600 per passenger, providing you arrive three hours late at your final destination.
Is 30 minutes enough time to catch a connecting flight?
Getting off a plane and walking to a distant departure gate can easily condense a 30-minute connection into almost nothing. Consider allowing at least 60 to 90 minutes for a U.S. domestic connection, and at least two hours for an international connection.
