What should I do if my connecting flight is delayed and I can't catch the next flight?

If the previous flight is delayed, the following measures can be taken: 1. It's best not to carry too much luggage on the flight that needs to transfer, so as not to waste time in consignment. 2. It can save a lot of time to propose to the flight attendants that they can contact the ground business for air transfer. Generally speaking, as long as they can do it, the flight attendants will try their best to contact. 3. If the last flight has been delayed, after the previous flight arrives and disembarks, take the boarding pass to the airline counter of the flight to issue a delay certificate, and change the next flight on the same day with the delay certificate.
