No more queues
You’ve likely had a flight canceled or delayed before if you fly a lot. It can be hard to reschedule your flight at a desk when the whole line behind you is trying to do the same.
A quick hack for these situations is to not stand in line like the rest of the passengers but call customer service. Someone is always ready to help, and you will be able to reschedule and book your flight in no time. You won’t have to stand in line ever again.
