An annual study of airline quality in the U.S. gave airlines the highest scores in the 26 years the rankings have been published.You may be wondering: How is that possible?Topping the Airline Quality Rating for 2016 were Alaska Airlines, Delta and Virgin America. At the bottom were Frontier, Spirit and ExpressJet. The rankings are based on performance numbers the airlines must report to the U.S. Department of Transportation, as well as complaints made by the public to the DOT about the airlines.The survey compiles data on four factors: on-time arrivals, involuntary denied boardings, mishandled baggage and customer complaints in 12 categories.The data show that in 2016, airlines improved on-time arrivals and baggage handling, while reducing denied boardings and consumer complaints.But the rankings reveal a few details worth examining.In 2016, 81.4 percent of flights arrived on time, compared with 79.9 percent in 2015. Great news, right? Well, maybe not."While [the airlines] aren't delaying too many flights, they're canceling a lot of them," says Brent Bowen, one of the report's authors and professor and dean of the College of Aviation at Embry-Riddle Aeronautical University.And it turns out that while airlines have to report their percentage of delayed flights to the Bureau of Transportation Statistics, they aren't required to similarly disclose canceled flights.Instead, those canceled flights are only captured (if at all) in customer complaints to the DOT.Still, the survey's authors give the greatest weight in the rankings to on-time arrivals, because consumers have said that's what's most important. "If you do that, you're good," says Bowen. "If you don't, you're bad."But perhaps you find flight delays less annoying than the array of aggravations that fall under the "complaints" rubric — such as fares, canceled and oversold flights, and problems with ticketing. Then you might want to avoid two airlines in particular: Spirit and Frontier. While both airlines had complaints go down since 2015, complaints about those two airlines are significantly higher than the industry average.Which brings us to the biggest lesson from this survey: If you're mad at an airline, don't complain only to the airline. Complain to the Department of Transportation, too.Only complaints lodged with the DOT are included in surveys like the Airline Quality Rating. So if you call Spirit or Frontier to complain about a litany of fees or a canceled flight, only the airline hears about it. Complaining to the DOT, meanwhile, can potentially lead to bigger changes:
- Alaska Airlines
- Delta Air Lines
- Virgin America
- JetBlue
- Hawaiian Airlines
- Southwest Airlines
- SkyWest Airlines
- United Airlines
- American Airlines
- ExpressJet
- Spirit Airlines
- Frontier Airlines
