TSA screened 204,152,406 passengers at security checkpoints nationwide between June 21 and September 7, 2026, about 5.76 million fewer than the 209,910,442 people it screened over the same stretch in 2025, according to TSA’s own checkpoint travel numbers. That works out to a 2.7% year-over-year decline across the entire summer travel season.

The drop runs against the grain of what forecasters were predicting just weeks before the season started. AAA projected a record 72.2 million Americans would travel at least 50 miles from home for the July 4th holiday alone, according to AAA’s own July 4th travel forecast. “While the overall number of Independence Day travelers appears to be plateauing, we’re still expecting record volumes this year,” said Stacey Barber, AAA’s vice president of travel, in the same release.
TSA’s checkpoint data tells a different story once the holiday crowds thin out. The final ten days of June came in roughly 1.8% below 2025 levels. July held closer to that pace, with checkpoint totals down about 2.1% year over year despite the AAA forecast. August delivered the steepest decline of the summer, with checkpoints screening about 76.8 million travelers compared to roughly 80.3 million in August 2025, a drop of 4.4%.
By the first week of September, the pattern nearly reversed. TSA screened about 16.44 million passengers in the September 1-7 window this year, essentially flat with the 16.41 million screened during the same week in 2025, suggesting the summer slowdown eased as the season wound down.
The daily average tells the same story in smaller numbers. Checkpoints processed roughly 2.58 million travelers a day on average this summer, down from about 2.66 million a day in 2025, a gap of roughly 73,000 people every single day for eleven straight weeks. Spread across an entire season, that’s the kind of steady erosion that shows up in airline load factors and hotel occupancy long before it becomes an obvious headline number.
Key Points
- Summer 2026 checkpoint volume fell 2.7% year over year, per TSA.gov.
- August posted the sharpest monthly decline, down 4.4% from August 2025.
- The decline came even as AAA forecast record July 4th travel volumes.
Airlines have already begun adjusting capacity on some domestic routes heading into fall, a sign carriers are treating the summer dip as more than a one-season blip. Travelers weighing shoulder-season trips may find the softer demand translates into more available seats and less competition for peak departure times, even as next year’s forecasts start from a lower baseline.
