Milwaukee Mitchell International Airport’s pandemic rebound hit a speed bump in 2025, with passenger traffic slipping for the first time in years. The airport finished the year with 5,874,372 travelers, which is 441,873 fewer than in 2024, a 7% drop that knocked MKE back under the six‑million mark it had just cleared the year before.
Numbers behind the decline
According to Milwaukee Mitchell International Airport, total traffic in 2025 came in at 5,874,372 passengers, down from 6,316,245 in 2024. Month‑by‑month reports show that March and the peak summer stretch lagged their 2024 totals, which was enough to drag the full year into negative territory.
Airlines scaled back in key months
Airline schedule moves did plenty of damage to MKE’s numbers. As reported by Urban Milwaukee, JetBlue went from 64 landings and 10,959 passengers in March 2024 to just two landings and 209 passengers in March 2025. Southwest, the airport’s largest carrier, also trimmed its March schedule year over year, with 72 fewer landings and an estimated 21,892 fewer passengers in that single month.
Spirit’s pullback widened the gap
The picture got even grimmer when Spirit stepped back. As reported by Hoodline, Spirit’s exit from Milwaukee came as the ultra‑low‑cost carrier restructured and cut routes. In related restructuring filings, Business Insider noted that Spirit listed roughly $8 billion in debt. Company balance‑sheet figures filed with the U.S. Securities and Exchange Commission show Spirit Aviation Holdings carrying liabilities in the 8 to 9 billion dollar range, a financial load that helps explain why the airline has been pulling back from smaller markets like Milwaukee.
What officials are planning
Milwaukee County has already baked weaker traffic into its planning. The county’s 2026 budget summary, reported by WTMJ, projects about 5.99 million passengers for 2026 and flags softening demand, rising fares, and employment worries. Airport director Brian Dranzik cautioned last fall that “consumer demand for air travel was softening” and said the airport authority was reforecasting passenger expectations going forward, according to Urban Milwaukee.
What this means for travelers
The mix of thinner airline schedules and one fewer ultra‑low‑cost player could leave travelers with fewer nonstop choices and some upward pressure on fares in certain markets, industry watchers say. MKE’s surge in 2024, when the airport handled more than 6.3 million passengers, shows how sharply traffic has swung and why airlines will be watching demand like hawks, per FOX6.
Airport officials say they will keep a close eye on bookings and work with airlines as they reshape schedules, while county planners fine‑tune the 2026 budget. Travelers and local businesses, meanwhile, will be watching to see whether carriers restore seats for the spring and summer rush or keep that capacity parked elsewhere.
