Allegiant Air on-time performance

Leaving on time and arriving on time are two different numbers

Pushed back on time

77.2% Left the gate less than 15 minutes behind the scheduled time.

Reached the gate on time

75.9% Arrived less than 15 minutes behind the scheduled time.

Cancelled

1% Share of scheduled flights that never flew.

Typical delay when late

86 min Averaged over flights 15 minutes or more behind.

An airline can leave late and still arrive on time if the schedule has padding in it, or leave on time and lose the margin in the air. A cancelled flight is neither on time nor late — it drops out of both rates entirely, which is why the cancellation figure has to be read alongside them rather than after them.

What the delays were put down to

Airlines file a reason with every arrival running 15 minutes late or more. The delay minutes on late Allegiant Air arrivals break down with 38.5% put down to late-arriving aircraft and 32.1% to airline operations.

Late-arriving aircraft is the knock-on category: the plane came in late, so it went out late again. It is why a 7am problem in Newark is still a problem in Denver at dinnertime, and why it is usually the biggest slice on the bar.

Month by month, July 2023–June 2026

The same figure as the board row above, one month at a time. Three years is enough to show the summer trough and the autumn recovery repeating, which is the point of plotting it rather than quoting a single month.
