From Jan. 1 through Dec. 31, more than 28.3 million passengers came through the airport.
That surpasses the previous record set in 2023 of nearly 27 million and a 5.2% year-over-year increase.
Airport officials attribute the growth to an increase in domestic passengers, which grew by almost 2 million compared to 2023.
The number of international passengers stayed roughly the same at 1.3 million.
Salt Lake City Department of Airports Executive Director Bill Wyatt says, “The addition of new nonstop destinations—thanks to our hub carrier Delta Air Lines—boosted passenger numbers as did our added gate capacity, which attracted new airlines to SLC.”
Since opening Phase 1 of the renovated airport in 2020, four new airlines have been added: Air Canada, Avelo, Hawaiian, Spirit and Sun Country.
In May, Canadian carrier WestJet will take off from Salt Lake with nonstop service to Edmonton, Alberta.
Changes to the airport are designed to accommodate 34 million passengers at the full build out of Phase 4, which is anticipated to open in fall 2026.
