Spirit Airlines will connect Fort Lauderdale with Key West.
Meanwhile, discount competitor Frontier Airlines will enter Richmond, Va.; Corpus Christi, Texas; and Tulsa, Okla.
The flights to and from Fort Lauderdale will be Spirit's first to Key West. They'll operate four times weekly beginning Nov. 6, then switch to daily on Dec. 18.
Spirit will be the lone carrier flying between Fort Lauderdale and Key West. Florida regional airline Silver Airways serviced the route before ceasing operations last month. Travelers instead often drive to Key West from Fort Lauderdale, a journey of approximately four hours.
Spirit is marketing the new route to connecting travelers. A company press release touted easy connections to Key West via Fort Lauderdale from Atlanta, Boston, Chicago, Dallas, Detroit, Houston, New York and Philadelphia.
Frontier's new routes from Denver
Frontier's home base of Denver will be the focal point of service from the carrier's three new destinations.
Flights connecting Corpus Christi with Denver will operate twice weekly beginning Oct. 9. Flights between Richmond and Denver will operate twice weekly beginning Oct. 19. The airline will also connect Richmond to Atlanta twice weekly beginning Oct. 17.
Tulsa-Denver service will be twice weekly starting Oct. 12. Frontier previously served as many as five cities from Tulsa, Cirium flight schedule data shows, but hasn't flown there since suspending Denver service in March 2022.
Frontier will compete against United and Southwest on both Denver-Richmond and Denver-Tulsa. It will be the lone carrier connecting Denver and Corpus Christi.
