You may not always have a choice of which airport to fly into or out of, but the next time you do, you may want to consider San Diego.

That's because San Diego International Airport is the best in the United States, according to a new study by travel website The Points Guy.

Although it isn't always possible to choose which airport to fly into or out of - "if you're going to Disney, you pretty much have to fly into Orlando," Scott Mayorowitz, the site's executive news director, said in a call - there are other scenarios where travelers might be able to choose between a couple of airports equidistant from your actual destination, or where to spend a few hours in between connecting flights.

When the choice exists, which airport you elect can make the difference between a relaxing wait with a snack and Wi-Fi, or a frustrating struggle as you watch delays mount up.

For the study, The Points Guy staff compiled data from the 50 busiest US airports by number of passengers, focusing on 34 factors including proportional number of delays and cancellations, average prices for ride-hailing services, number of restaurants and lounges, and average security wait times.

Here are the winners and losers among the 50 busiest airports.
