If you are unable to work it out with the connecting flight, please contact your airline right away.
Normally, the quickest way to deal with a missed connecting flight is to contact the airline agents at the airport. They are more aware of the current situation and can sometimes offer you a suitable solution. If you are stuck in a long line at the airport, try calling your airline or contacting their customer service.
When airlines offer a route with one or more connecting flights to take you from point A to point B, all intermediate connections are “protected”. In other words, if a leg of your flight is delayed and you are unable to catch the next plane, the airline will take care of you and make sure you arrive at your destination.
Affected passengers may be offered another flight to their destination or place of residence, as well as other necessary measures depending on the situation. Airline policies differ in this regard. Sometimes you can also get a refund for your trip.
