A flight diversion takes place when an aircraft has some kind of emergency that requires it to deviate from its original course. A diversion can happen at any time for a number of reasons and it is something that just has to be adapted to, often at the last minute. It can be due to a medical emergency, a technical issue, bad weather, or an unruly passenger. Most of these incidents are unpredicted and the flight crew and flight attendants have to act in accordance to keep all onboard safe and sound.
