Sun Country Airlines Drastically Cut Flights Because Its Pilots Left For Delta, CEO Admits

Sun Country Airlines is confronting a severe pilot attrition crisis at its Minneapolis-St. Paul (MSP) hub, forcing the carrier to slash its September 2026 schedule by nearly 40% year-over-year. Scheduling data from Cirium shows Sun Country dropping from 567 flights and 105,477 seats in September 2025 to just 344 flights and 63,866 seats this September, with available seat miles falling 37.3%. Allegiant Air CEO Greg Anderson, whose company acquired Sun Country, confirmed on the carrier's Q2 earnings call that the cuts stem directly from junior MSP-based pilots departing for Delta Air Lines, which has reportedly doubled or more its hiring at the Twin Cities hub. Anderson's characterization of pilots wanting "to work for a full-service carrier" underscores a structural vulnerability facing low-cost and ultra-low-cost carriers that have historically served as stepping-stone employers for pilots building hours toward major-airline careers.

This situation illustrates a persistent dynamic in the U.S. pilot labor market that predates the post-pandemic hiring boom but has intensified as legacy carriers resume aggressive recruiting after a brief pause in major hiring during 2023-2025. Sun Country, like many ULCCs and regional carriers, has functioned as a training ground where junior pilots accumulate turbine time and multi-crew experience before flowing to majors offering superior pay scales, quality-of-life provisions, widebody international flying, and stronger retirement benefits. When a dominant hub carrier like Delta—which controls 77.5% of all MSP departures—ramps up hiring in the same metro area where a smaller competitor is based, the smaller carrier has little defense against attrition beyond raising pay or accelerating upgrade timelines, both of which carry significant cost implications for an airline already operating on thinner margins than a legacy full-service carrier.

For working pilots, this story is a useful data point on career-path leverage and hub geography. Pilots based at or near MSP with Sun Country now have a clear, well-documented precedent showing that proximity to a major's crew base translates into real hiring opportunity, and it reinforces the broader industry pattern where ULCC and regional pilots treat their current seat as transitional rather than terminal. For flight departments and HR planners at smaller carriers, the episode is a cautionary tale about retention risk concentration: when a huge percentage of a workforce is junior and geographically co-located with a major's hiring pipeline, schedule reliability becomes hostage to a competitor's staffing decisions. This is particularly relevant for Allegiant's broader strategy following its Sun Country acquisition, as network planners must now factor pilot-supply risk into capacity commitments at hub airports shared with legacy carriers.

More broadly, the MSP situation reflects how consolidation and hub dominance shape not just route economics but labor markets. With Delta controlling nearly four out of five flights at MSP and expanding both domestic and international mainline service, its hiring gravity effectively sets the local labor terms for every other carrier operating there, including American, United, Southwest, and Sun Country. As major carriers resume steady pilot hiring following the industry-wide slowdown of the mid-2020s, other regional and ULCC operators should expect similar attrition pressure wherever they share crew bases with a legacy hub carrier, making retention economics—not just fleet and route planning—an increasingly central variable in capacity forecasting across the industry.
