A flight delay is a when an airline flight takes off and/or lands later than its scheduled time. The Federal Aviation Administration (FAA) considers a flight to be delayed when it is 15 minutes later than its scheduled time. A cancellation occurs when the airline does not operate the flight at all for a certain reason. When flights are canceled or delayed, passengers may be entitled to compensation due to rules obeyed by every flight company, usually Rule 240, or Rule 218 in certain locations. This rule usually specifies that passengers may be entitled to certain reimbursements, including a free room if the next flight is the day after the canceled one, a choice of reimbursement, rerouting, phone calls, and refreshments. When a flight is delayed, the FAA allocates slots for takeoffs and landings based on which flight is scheduled first. ==Causes== Since 2003, the United States Bureau of Transportation Statistics has been keeping track of the causes of flight delays.〔(【引用サイトリンク】title=Airline On-Time Statistics and Delay Causes )〕 Some of the causes of flight delays are as follows: *Maintenance problems with the aircraft〔(【引用サイトリンク】title=Understanding the Reporting of Causes of Flight Delays and Cancellations )〕 *Fueling〔 *Extreme weather, such as tornado, hurricane, or blizzard〔 *Airline glitches.
