What steps do you need to take when an airline cancels your flight?

Answer 1

Whena flight is cancelled, you must call the airline as soon as possible to find an alternative flight, or get a refund.
do this quickly before the other passengers also call and fill up the next available flights.
You can ask for the airline to put you on another airline, under certain conditions. Sometimes they will depending on the airline and how restrictive your ticket is. If you are stuck halfway to your destination, they may also pay for a hotel room, if it is not a weather related cancellation.
