San Diego International Airport Served 15.6 Million Passengers in 2021

Tuesday, February 8, 2022

SAN DIEGO – February 8, 2022 – San Diego International Airport (SAN) served 15.6 million passengers in 2021, a 69 percent increase over 2020’s passenger number of 9.2 million. The airport added 18 new routes to both domestic and international destinations and one new carrier.

“The aviation industry continued to be impacted by COVID-19, but we saw improvement in passenger numbers once vaccines were available and people felt more comfortable traveling by air again,” said Kimberly Becker, President & CEO of the San Diego County Regional Airport Authority. “Airlines added new destinations from SAN and flights to most international destinations were resumed once regulations and restrictions were eased. Throughout the pandemic, our airport has remained open providing services to those traveling and maintaining our high standards of cleaning for the health and safety of passengers.”

Southwest Airlines continued to be the number one carrier at SAN in 2021 at 33 percent seat share. Southwest Airlines expanded its presence with service to three additional Hawaiian destinations and six new routes overall.

Alaska Airlines maintained the number two spot with 19 percent of total seats, growing five percent from their total seat share in 2019 and adding new service to five cities.

Allegiant Air had the greatest capacity growth out of all the carriers serving the airport. Allegiant Air grew by 77 percent, adding five new routes to its summer seasonal service.

Swoop, a Canadian-based carrier, began service at SAN providing nonstop service to Edmonton, Alberta, Canada.

Despite the growth year over year, passenger traffic in 2021 was down 38 percent over 2019’s record-breaking year of 25.2 million total passengers. Detailed reports of SAN air traffic statistics are available at
