Airports are usually very busy the day after Christmas, and for the 2025 holidays it is expected to be one of the peak travel days of the entire season in the U.S. Crowds, security lines, and parking will often feel closer to a summer or Thanksgiving rush than to a normal winter weekday.

What December 26 Usually Looks Like

  • Travel organizations and airline groups flag December 26 as one of the “worst” or most congested days to fly during the Christmas–New Year window, with passenger volumes well above a typical day.
  • Historic TSA data and travel analyses show that the post‑Christmas period (roughly December 26–28) stays extremely busy as people head home or continue on to New Year’s destinations.
  • Major airports expect sustained high throughput rather than a single spike: mornings and late afternoons are often the most crowded at security and check‑in.

How 2025 Is Shaping Up

  • For the 2025 winter holidays, U.S. air travel is projected to set or approach record volumes, with more seats scheduled and more total travelers than in recent years.
  • Local airport forecasts (for example, Houston and Pittsburgh) show millions of passengers moving through between roughly December 18 and early January, with December 26–29 specifically called out as peak departure days.
  • Travel and government agencies warn of crowding not just at security, but also on access roads, parking, and baggage claim due to the sheer number of flights scheduled just after Christmas.

Tips If You’re Flying the Day After Christmas

  • Arrive earlier than normal: at least 2 hours for domestic and 3 hours for international is commonly recommended during this period, with extra buffer if you fly early morning or late afternoon.
  • Expect premium on convenience: close‑in parking, priority security, and nonstop flights may sell out or be more expensive during this peak.
  • If you want fewer crowds in future years, travel experts repeatedly suggest flying on Christmas Eve/Day or on New Year’s Eve/Day instead, which tend to be noticeably quieter than December 26.
