Flight delayed, canceled or oversold (1 of 10)
You have all your bags packed, and after weeks of anticipation you finally reach the airport ready for your vacation. Then you discover that the airline has canceled or delayed your flight. It's a horrible way to start your trip, and if you are lucky, it'll only be a couple of hours delay. But I've also lost 2 days of my trip because the airline was not able to rebook me onto an earlier flight.
