If it felt like airports were a little less crowded this summer, the numbers suggest you weren’t imagining it. According to TSA checkpoint data, the number of passengers passing through U.S. airport security checkpoints this summer was noticeably lower than during the same period last year.
I compared TSA checkpoint numbers from June 21 through September 7, 2026 with the exact same dates in 2025. Over those 79 days, TSA officers screened 204,152,406 passengers in 2026, compared with 209,910,442 passengers in 2025. That’s a difference of 5,758,036 travelers, or a 2.7% year-over-year decline.
To put it another way, TSA screened an average of about 2.58 million passengers per day during this period in 2026, compared with approximately 2.66 million per day last year. That’s roughly 73,000 fewer passengers passing through TSA checkpoints every day.
The slowdown became more pronounced as summer progressed
What’s interesting is that the decline wasn’t evenly spread throughout the summer. From June 21 through June 30, TSA screened approximately 27.6 million passengers, down 1.8% from the same dates in 2025. July was also lower, with approximately 83.3 million travelers screened compared with 85.1 million in July 2025. That’s a decline of about 2.1%.
But August is where the difference really stands out. TSA screened approximately 76.8 million passengers in August 2026, compared with 80.3 million in August 2025. That’s about 3.54 million fewer passengers in a single month, representing a sizable 4.4% year-over-year decline.
Interestingly, the trend reversed during the first week of September. From September 1 through September 7, TSA screened 16.44 million travelers, slightly more than the 16.41 million screened during the same dates in 2025. That’s an increase of about 0.2%.
Be careful comparing individual TSA dates
There’s one important caveat when looking at TSA’s daily checkpoint numbers. The days of the week don’t line up from one year to the next, and airport traffic can vary dramatically depending on whether it’s a Tuesday, Friday or Sunday. For example, comparing August 9, 2026 directly with August 9, 2025 isn’t necessarily an apples-to-apples comparison because those dates fell on different days of the week.
That’s why I think the broader monthly and summer totals provide a much better indication of what’s happening with air travel demand. And the broader numbers are pretty compelling.
From June 21 through September 7, U.S. airport security checkpoints processed nearly 5.8 million fewer passengers than during the same period last year.
That’s especially interesting because for the past several years, the travel story has largely been about record-breaking crowds and seemingly endless demand. We’ve seen TSA repeatedly announce some of its busiest travel days ever. This summer’s numbers suggest that growth has cooled, at least for the moment.
What travelers should take away from the numbers
Of course, a 2.7% decline doesn’t mean airports suddenly became empty. More than 204 million people still passed through TSA checkpoints during this 79-day period, and plenty of airports experienced extremely busy days.
The busiest day in the 2026 period I analyzed was June 21, when TSA screened 2,981,485 passengers. There were also numerous days when checkpoint volume topped 2.9 million.
So I wouldn’t show up at the airport later just because overall passenger numbers are down. Security lines can still be long, especially during peak travel periods and at the country’s busiest airports.
But after years of seemingly nonstop growth in air travel, these numbers are worth monitoring. The biggest question now is whether August’s 4.4% decline was just a late-summer blip or the beginning of a broader slowdown in U.S. air travel.
