Airlines are stepping up with new flights to fill the gap left by Spirit Airlines.
American Airlines, Avianca, Breeze Airways, Delta Air Lines, Frontier Airlines, JetBlue Airways, Southwest Airlines and United Airlines have all added flights and routes in former Spirit markets since the discount carrier shut down May 2, airline statements and schedule data from aviation analytics firm Cirium show.
Spirit flew just under 2% of all domestic flights and seats, according to Cirium data — not a large airline but not an insignificant one either. Its five largest destinations (by seats) were: Fort Lauderdale-Hollywood International Airport (FLL), Orlando International Airport (MCO), Newark Liberty International Airport (EWR), Detroit Metropolitan Wayne County Airport (DTW) and Hartsfield-Jackson Atlanta International Airport (ATL).
Other airlines’ additions, at least so far, are at airlines one would expect: Delta at DTW, JetBlue at FLL, and Southwest at MCO and Harry Reid International Airport (LAS) in Las Vegas — all existing bases or hubs for each respective carrier.
No airline is taking advantage of Spirit’s collapse to open a new base or hub — at least not yet.
Here are the airlines that have added former Spirit routes in the past week (but note that future schedules are subject to change):
