03. Flight Cancelled? Call Immediately
This is one of the problems on the airline behalf that many times they didn’t inform their passengers about the cancellation of their flights. Now, if they inform you then one thing you must do at once is to book your seat in the very next flight. You should call immediately to the customer service line because every second counts in such a situation. If you didn’t, there is every possibility that you’ll be left out in the next flight.
