Day by day

Which day of Fourth of July week ran best

Getting away was harder than coming back. The first day, Saturday 1 July at 68.8% on time, 1.1 points below the 69.9% of ordinary Saturdays, set the low mark. The best day was Tuesday 4 July at 83.3%, while Thursday 6 July was the busiest, with 19,616 flights scheduled. 2 of the 7 days ran below the figure for the same weekday in the baseline weeks.

Day-by-day change against normal weekdays: Sat 1 −1.1, Sun 2 +2.9, Mon 3 +11.4, Tue 4 +9.6, Wed 5 −1.8, Thu 6 +1.9, Fri 7 +3.7 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.

Here “normal weeks” means the same day of the week in the baseline weeks, so a Sunday is set against the baseline Sundays.

Departure window

The best time of day to fly it

Departure time mattered more than the date. Flights leaving 5am–8am ran 89.9% on time, and by 5pm–8pm that had fallen to 59.6%, 30.3 points lower. The 8am–11am window moved most against its normal weeks, 5.2 points better than 79.9%.

Airport by airport

Airports over Fourth of July week 2023

Among large airports the on-time rate ran from Baltimore (BWI) at 57.9%, Orlando (MCO) at 58.0% and Miami (MIA) at 60.8% at the low end to Honolulu (HNL) at 90.0%, Kahului (OGG) at 89.0% and Portland (PDX) at 85.3% at the top. Jacksonville (JAX) fell furthest against its own normal weeks, from 67.6% to 65.0%. Measured against each airport's own normal weeks, 4 of 53 did worse.

By volume the holiday ran through Atlanta (ATL, 6,071 departures, 75.6% on time), Dallas-Fort Worth (DFW, 5,628 departures, 71.1% on time) and Denver (DEN, 5,516 departures, 63.9% on time), which handled 13% of all departures between them.

Not every airport struggled: Tampa (TPA, +13.0 points), Fort Lauderdale (FLL, +12.1 points) and Boston (BOS, +9.2 points) improved on their usual on-time rate.

Delay length varied widely by airport. Delayed departures from Jacksonville (JAX) averaged 101 minutes, against 87 in its normal weeks, the longest of any large airport; at Burbank (BUR) the average was 43 minutes.

Holiday traffic did not rise evenly. Daily departures rose most at Burbank (BUR, +2%), Kahului (OGG, +0%) and Oakland (OAK, −0%), and fell most at New York (LGA, −12%). None of the three ran worse than usual, so the extra flights were absorbed.

What to do with this

Planning around Fourth of July week

If 2023 is any guide: Tuesday 4 July was the best day to fly; and book before the evening, since 5pm–8pm departures ran 30.3 points worse than 5am–8am ones. Treat that as one data point; the Fourth of July week overview shows which of these patterns repeat.

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.
