Data through June 2026 · Bureau of Transportation Statistics

Leaving on time and arriving on time are two different numbers

Pushed back on time
82.4% Left the gate less than 15 minutes behind the scheduled time.
Reached the gate on time
80.5% Arrived less than 15 minutes behind the scheduled time.
Cancelled
1.3% Share of scheduled flights that never flew.
Typical delay when late
84 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 SkyWest Airlines arrivals break down with 48.9% put down to airline operations and 20.8% to late-arriving aircraft.

Late-arriving aircraft 20.8% Airline operations 48.9% Air traffic & airport volume 15.7% Severe weather 14.5% Security 0.1%
  • Late-arriving aircraft 20.8%
  • Airline operations 48.9%
  • Air traffic & airport volume 15.7%
  • Severe weather 14.5%
  • Security 0.1%

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.

Share of SkyWest Airlines flights that arrived on time, month by month. The scale runs 65% to 90%; the marked points are the lowest month and the most recent one.

The name on the ticket may not be this one

SkyWest Airlines is a regional airline. It flies short and medium routes under the colors and flight numbers of the major carriers — your ticket may well say American, Delta or United — and it files its own on-time record with the government under its own name. That is why it appears here as an airline in its own right, and why its numbers are not folded into the brand on the boarding pass.

Against the rest of the industry

One airline in isolation is hard to read. The comparison table puts all 15 reporting carriers side by side on the same three measures.

Questions about SkyWest Airlines

How often is SkyWest Airlines on time?
80.5% of the 2,317,954 flights SkyWest Airlines actually flew arrived less than 15 minutes behind schedule, July 2023 through June 2026. On departures the figure was 82.4%.
Why are SkyWest Airlines’ departure and arrival numbers different?
Departure on time means pushback less than 15 minutes behind schedule; arrival on time means reaching the gate less than 15 minutes behind schedule. SkyWest Airlines pushed back on time more often than it parked on time — 1.9 points more often, the gap that opens up in the air and on the taxiway.
What is SkyWest Airlines’ cancellation rate?
1.3% of scheduled SkyWest Airlines flights were cancelled, July 2023 through June 2026. Cancellations sit outside the on-time rate entirely: a cancelled flight is neither on time nor late, which is why the two numbers have to be read together.
What causes SkyWest Airlines delays?
Of the delay minutes on late SkyWest Airlines arrivals, 48.9% were filed as airline operations and 20.8% as late-arriving aircraft. Severe weather accounted for 14.5%, though that is not the whole weather story: conditions bad enough to slow the system as a whole are filed under air traffic and airport volume instead.
Is SkyWest Airlines the airline on my ticket?
SkyWest Airlines is a regional airline. It flies short and medium routes under the colors and flight numbers of the major carriers — your ticket may well say American, Delta or United — and it files its own on-time record with the government under its own name. That is why it appears here as an airline in its own right, and why its numbers are not folded into the brand on the boarding pass.
