Christmas day can be a busy time at airports, as many people travel to be with their families during the holiday season. The day before Christmas and the day after Christmas can also be busy, as people return home from their travels or go on vacations. Airports may experience higher passenger volumes and increased demand for flights during the Christmas season, which can lead to longer lines and longer wait times. It's a good idea to plan ahead and arrive at the airport early, if possible, to avoid any potential delays or disruptions.
