Day by day

Which day of Fourth of July week ran best

As so often, the trip home was the hardest part. Monday 7 July at 67.6% on time, the closing day of the window, 4.4 points below the 72.0% of ordinary Mondays. The best day was Friday 4 July at 83.5%, while Monday 7 July was the busiest, with 21,499 flights scheduled. 2 of the 7 days ran below the figure for the same weekday in the baseline weeks.

Each day of the window, set against its weekday in normal weeks: Tue 1 −3.3, Wed 2 +2.0, Thu 3 +2.0, Fri 4 +13.8, Sat 5 +7.4, Sun 6 +2.6, Mon 7 −4.4 points. No more than one day in a row ran below the weekday baseline, so the weak days were isolated rather than a sustained slowdown.

What to do with this

Planning around Fourth of July week

Practical points from 2025: avoid the final day of the window, the worst of 2025; book before the evening, since 5pm–8pm departures ran 34.2 points worse than 5am–8am ones; and allow extra connection time at Miami (MIA) and Las Vegas (LAS). The pattern across years, on the Fourth of July week overview, is the safer guide.

On time means arriving less than 15 minutes after the scheduled gate time. Average delay counts delayed flights only; cancellations are a share of every scheduled flight. A holiday is compared with the two weeks either side of it, leaving out days that belong to other holidays. The measurable-effect test asks for 3 points of on-time rate, 5 minutes of average delay or 2 points of cancellations; airports, routes and carriers need 500 flights in the window to be ranked. The US DOT publishes on-time data about two months after the month it covers.
