You wait at the gate desk when your flight is cancelled
Don’t get discouraged over a cancelled flight just yet. The best way to handle an off-schedule flight is to call the airline as you wait in line at the ticket desk. There’s a good chance you’ll reach a phone agent first. Equally as important, you won’t have to negotiate with the same frazzled agent who’s dealt with dozens of similarly disgruntled fliers. These are the things airlines won’t tell you (but every flier should know).
