Frontier adds 4 routes, fills gap left by Spirit Airlines at several major airports

Frontier Airlines is picking up where Spirit Airlines left off at several busy airports.In the wake of Spirit’s collapse, Frontier on Tuesday announced it’s adding four new routes, several of which were staples for its defunct rival.The new service unveiled this week includes new flights to South Florida, Orlando, the Caribbean and Detroit — all cities where Spirit previously had a big presence.Elsewhere, Frontier will add new Florida service from its home base at Denver International Airport (DEN). It will also try to make up ground in Detroit, a major Midwest hub where Spirit had been the top challenger to Delta Air Lines, the No. 1 carrier in town.Read more: Spirit is gone.
