The MOST and LEAST Reliable Airlines in the U.S.

There have been a lot of issues with air travel lately.

Have you been keeping up with the travel news?

We’ve seen delays, cancelations, staffing shortages, and more. But, things could be changing soon, as several airlines have new deals to hopefully help with these kinds of issues. So, which airline is the MOST reliable, and which is the LEAST? We’re going to break it down!

We’re going to take a look at the most and least reliable airlines based off of on-time arrivals in May of 2022. All of the data is from the Air Travel Consumer Report from the Office of Aviation Consumer Protection. Note that a flight is considered to be “on-time” by this report if it operated less than 15 minutes after the scheduled time shown in the carriers’ Computerized Reservations Systems (CRS).

Most Reliable

The number 1 most reliable airline according to the report was Hawaiian Airlines, which had 86% of its arrivals be on time in May of 2022.


The number 2 spot went to SkyWest Airlines with 83.6% of on-time arrivals, and the number 3 spot goes to Horizon Air with 83.4% of on-time arrivals.

Which airline is your favorite?

In 4th place, there’s Envoy Air at 81.5%, and in 5th is Endeavor Air with 81%.

It’s also important to note that Delta Air Lines was very close to being in the top 5 at 80.3% of flights coming in on time.

Note that a lot of the bigger airlines are getting reports from more airports, with some having pretty significant differences. For example, while Hawaiian Airlines is number 1, they only had 22 airports report this data. Meanwhile, Delta Air Lines had 130 airports report, so with more airports comes more opportunities for late arrivals. SkyWest had the most airports reported at 243, so that number 2 spot is pretty impressive!

Where are you flying next?

Now, keep in mind that this was just for May of 2022, and things continue to change in the air travel world. There have been more and more delays, as well as staffing shortages and cancelations. But, it’s still good info to know if you’re deciding between two different airlines!
