Lone Star expansion: Low-fare Spirit Airlines plans to add 10 new routes from Houston

Spirit Airlines Inc. said Friday it plans to add 10 new routes from Houston next year, which would nearly double its destinations from Bush Intercontinental Airport.

The low-fare airline said it will begin flying to Baltimore and Tampa, Florida, in March; and to Oakland, California, in April.

Spirit is seeking foreign government approval to begin flights in May to Cancun, Los Cabos and Mexico City; Managua, Nicaragua; San Jose, Costa Rica; San Pedro Sula, Honduras; and San Salvador, El Salvador.

Southwest Airlines Co. is building an international terminal at nearby Hobby Airport to begin overseas flights from Houston next year.
