After a year of pandemic-induced isolation in the U.S., air travel began to pick up again in 2021. Many people traveled for work, while others cooped up at home decided to go on a much-needed vacation.

Last year, 674 million passengers flew on U.S. airlines, according to the Bureau of Transportation Statistics. While that number seems like a big one—it's 83% more than the year before—it still remains below pre-pandemic levels.

To shed more light on the state of travel in the U.S., luggage storage app Bounce examined flight data from the Department of Transportation to find the most popular destinations from major U.S. airports in 2021, the latest information available. The data only includes domestic flights, as reported by U.S. airlines. In the event of a tie, the most popular location in 2020 was used.

Unsurprisingly, the most popular destinations were warm-weather spots like Los Angeles and Orlando; however, there are a few surprises on the list, as well.

As the country continues to emerge from the lingering pandemic, new travel trends have also emerged. Corporate travel—which made up a large portion of air and hotel spending—has made a slow rebound. Business travel is unlikely to return to pre-pandemic levels this year, according to a 2022 Deloitte outlook report.

The age of traveles may also be shifting. Travelers over age 55, who were projected to be a large share of travelers before the pandemic, are now less likely than 18-34 year olds to take a trip, the report also found. This continues the trend in 2021, when 18-34 years took an average of 2.7 trips. This was higher compared to 35-54 year olds (2.4 average trips) and those 55 years and older (1.7 average trips).
