Counted from published nonstop services rather than live schedules, so this describes the shape and reach of Frontier Airlines’ network - its bases, how far it ranges and how much it leans on partners - rather than today’s timetable.
On codeshares: about 51% of these routes are marketed by Frontier Airlines but flown by a partner. It matters at the airport: baggage rules, seat selection and lounge access usually follow the operating carrier, not the one on your booking reference.
