Hello!
Two of my flights have been cancelled and I don't know what procedure should I do. Thanks for any help you may provide.
With a mouseover you get the info why those flights have been cancelled.
If the next flight starts from the current position of the aircraft, you don't have to do something. Otherwise you have to start a transfer flight (if there is enough time) to one of the next destinations or cancel the next flights until they start again from the current location.
