Flight delays are usually unexpected, and a flight may land or take off later than it was expected to. Either way, it means that your flight is not going to follow schedule. A lot of airlines cancel flights due to weather conditions. This is actually the most popular reason for a cancellation. The other reason may be mechanical issues. Either way, flight delays are an inconvenience to passengers. They also cost airlines billions of dollars each year. It's not a win-win situation. Delayed passengers may experience anger and frustration. This group of guys reacted differently when they learned of a flight delay. I don't know whether to watch them or join them. It's so infectious.
