The Airlines Most Likely to Suck, According to Department of Transportation Data

If you’re booking summer travel and faced with a choice of similarly priced tickets on different airlines, it’s worth doing a little homework first. The Department of Transportation recently released its Air Travel Consumer Report, and included in its findings is data on the quality of services provided by each airline. Which is to say, you can figure out which one you need to avoid due to a poor track record with delays, cancellations, mishandled baggage, and more.

The raw data is pretty useless, but with a little effort and analysis—which I’ve provided below—it can help you make the most informed choice. The Department of Transportation filters much of their data through the 10 most-traveled domestic airlines (Alaska Airlines, Allegiant Airlines, American Airlines, Delta Airlines, Frontier Airlines, Hawaiian Airlines, JetBlue Airways, Southwest Airlines, Spirit Airlines, and United Airlines), so I’ve limited my exploration to these carriers.

Below, I’ve broken it down into four major headache-inducing categories; delays, cancellations, mishandled luggage, and overbooked/oversold flights. I’ve given the highest performing airline in each category 10 points; the second-highest performer 9 points, and so on. Each of the four categories are equally weighted, and the airline’s placement in each is added together for a total score. All data is as of March 2022, which is the most recent available, per the Air Travel Consumer Report.

Which airline is worst for delays?

According to the report, a flight is defined as on-time if it “operated less than 15 minutes after the scheduled time shown in the carriers’ computerized reservations systems.”

Fly Hawaiian, avoid JetBlue?

If you’re looking for the least stressful flight, your best bet is Hawaiian Airlines‚ at least according to Department of Transportation data. Obviously other variables go into booking an airline flight beyond this metric, most importantly price and availability. (While Hawaiian Airlines scored highly across the board, that’s not particularly useful to you if you’re not…flying to Hawaii.) But it gives you one more data point to work from debating between which major airline or budget carrier to choose.
