Please be advised that you should be at the airport 90 minutes before your SCHEDULED flight time. If your flight is delayed, you should NOT change your originally planned arrival time to the airport. Delayed times could be cancelled or changed, and the flight might actually leave on time. Most airlines require you to be in the gate area 30 minutes prior to the scheduled flight time, even if the flight gets delayed. Contact your air carrier for further details, or refer to their website regarding their individual rules, terms and conditions. It is always a good idea to double check displayed flight delay status by calling the airline 800 number or the airline website.
