Christmas, not summer, is the worst time to fly

The busiest and most chaotic time to travel is actually during the Christmas holiday season, not the summer, according to a former check-in agent. This is due to fewer flights operating on Christmas Day, despite high demand as people travel to see family and friends. Delays and cancellations are common during this period, often caused by weather or maintenance issues. Airports like London's Heathrow have seen record passenger numbers during the Christmas period, exceeding pre-pandemic levels. Overbooked flights and passenger displacement are also common issues.
