Jules Hunter, a teacher from Illinois, has to get to Rochester frequently.
Her son, who has a rare form of epilepsy, is part of a clinical trial at Mayo Clinic. They fly into the Rochester International Airport every other week.
But lately, as regional airports around the country see lower departure and seat numbers for passengers, Hunter said the family is concerned about fewer choices in flights needed to make her son's appointments.
"I'm worried about it," she said. "But we've been lucky so far."
The decline in departures and capacity can be tied to an ongoing pilot shortage across the country that is pushing airlines to send pilots where they are most needed – bigger hubs – while some smaller regional airports get left behind, said Jack Penning, a managing partner at Volaire Aviation Consulting.
Some regional Minnesota airports — like Duluth and Rochester — have seen declining seat availability. Other airports have been left unscathed.
Rochester departures dropped from 4,208 in 2018 to less than 2,000 this year, according to Airline Data Inc. Departure numbers for the current year are subject to change.
United Airlines left the Rochester airport late last year, a decision that airport Executive Director John Reed said can be attributed to the pilot shortage.
