Spirit Airlines

There is renewed speculation that Frontier and Spirit airlines might merge, according to published reports.

Low-cost carrier Spirit Airlines is expanding its non-stop service from Houston George Bush Intercontinental to 10 new destinations starting in Spring 2015, the airline said.

New changes proposed by the federal government aim to bring more transparency to how airlines charge for “certain basic airline services” above the base fare price, such as checked baggage. But the airline industry says the market can and does regulate itself and contends the new proposal is an overreach.
