Airport by airport

Airports over Fourth of July week 2024

Most large airports coped better than usual, and only 0 of 56 ran below their normal weeks. The weakest were Charlotte (CLT) at 66.7%, Houston (IAH) at 67.2% and Dallas-Fort Worth (DFW) at 71.0%; the strongest Kahului (OGG) at 91.1%, Salt Lake City (SLC) at 87.3% and Honolulu (HNL) at 87.2%.

The biggest airports carried the most weight: Denver (DEN, 6,227 departures, 80.1% on time), Atlanta (ATL, 6,185 departures, 77.3% on time) and Dallas-Fort Worth (DFW, 6,081 departures, 71.0% on time), together 14% of every departure in the window.

Best against their own normal weeks: Orlando (MCO, +19.4 points), Miami (MIA, +17.0 points) and Detroit (DTW, +15.4 points).

How long a delay lasted depended heavily on the airport. Delayed departures from Austin (AUS) averaged 111 minutes, against 74 in its normal weeks, the longest of any large airport; at Anchorage (ANC) the average was 42 minutes.

Some airports took far more of the holiday rush than others. Daily departures rose most at Kahului (OGG, +1%), San Francisco (SFO, +1%) and Honolulu (HNL, +1%), and fell most at Atlanta (ATL, −11%). The extra traffic did not cost them punctuality.

What to do with this

Planning around Fourth of July week

Lessons from 2024: avoid the final day of the window, the worst of 2024; and book before the evening, since 8pm–5am departures ran 22.6 points worse than 5am–8am ones. Those are one year's patterns; check them against the other years before relying on them.

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.
