The luggage storage app Bounce analyzed numerous factors to put together this list of the top-rated airlines in 2021. The best airlines boast high marks in convenience, with prompt arrival times and generous maximum baggage allowances. They provide small luxuries to passengers as well in the form of comfortable seats, robust inflight entertainment, and quality meals. Bounce also looked at the number of complaints filed against each company between January and June 2021 and the level of staff service.

Coming in at No.1 on the domestic list is Delta. In 2021, the airline received a relatively low number of complaints and made the second-best arrival times in the U.S. They were edged out in the latter category by Hawaiian Airlines, the No. 2 airline in the U.S. Horizon Airlines, Alaska Airlines, and JetBlue also made the top five.

On the global level, Ana All Nippon Airways was named the best airline overall. The Japanese company scored five out of five points in staff service and fours in food, comfort, and entertainment.
