Salt Lake City International Airport has become one of the fastest-growing large hub airports in the Mountain West. It combines a strong local market with a major connecting role for Delta Air Lines, and its rebuilt terminal complex has positioned the airport for another phase of growth.

How many passengers use Salt Lake City International Airport?
SLC handled a record 28.0 million passengers in FY2024, up from 26.4 million in FY2023. That was the airport’s strongest fiscal-year result on record and an important milestone because it pushed SLC beyond its pre-pandemic traffic levels.
The airport’s FY2024 annual financial report also notes that Salt Lake City had fully recovered from the pandemic by FY2023 and then moved higher again in FY2024. That is a stronger story than simple recovery. SLC is now operating in a fresh growth phase.
How many flights does SLC handle?
Through the 12 months ending August 2025, SLC recorded 332,652 total aircraft operations. For the first eight months of 2025 alone, the airport logged 225,304 operations, up nearly 2% from the same period in 2024.
That is roughly in line with the airport’s 2018-era flight totals, but passenger traffic is now materially higher because of larger aircraft, fuller flights, and an expanded terminal footprint.
International traffic at SLC
International traffic is still smaller than at coastal gateway airports, but it continues to grow. On a rolling 12-month basis through August 2025, SLC handled 1,451,673 international passengers, up 7.3% year over year.
That matters because it shows the airport’s network is getting deeper, not just busier.
Salt Lake City Airport revenue
The newest audited financial report I verified was the FY2024 ACFR, which clearly establishes FY2024 as the airport’s record traffic year and notes that the FY2025 budget assumed additional passenger growth. The older historical revenue figures from your original post are no longer the most useful lead metrics, so this rebuild shifts the emphasis toward current traffic and operating scale.
