Frontier Airlines expands again, adds four new cities

Frontier Airlines is adding four new destinations and adding three routes from its main base in Denver. The expansion comes just a week after the carrier revealed plans for a whopping 42 new nonstop routes. The latest announcement has Frontier adding service to four destinations it does not currently serve: Colorado Springs; Columbus, Ohio; Pittsburgh and San Antonio. Frontier will fly to three of those cities from Denver – all except Colorado Springs – effectively increasing its presence there. Denver is home to Frontier’s headquarters and is the airline’s main hub. Of the new destinations, Frontier’s most-robust debut will come in Pittsburgh. The airline will begin flying there in June with nonstop service to five destinations: Atlanta, Chicago O’Hare, Denver, Las Vegas and Orlando. The Denver and Las Vegas routes will feature daily flights. Frontier will fly 3 or 4 flights a week on the other routes.<br/>
