Airtran & Frontier

Low-fare carriers AirTran Airways (AAI - commentary - Cramer's Take - Rating) and Frontier Airlines (FRNT - commentary - Cramer's Take - Rating) say they will team up in a partnership to jointly offer frequent flier miles to passengers on either airline.

The move enables each carrier to use its partner's frequent flier programs to attract new passengers from outside its network. AirTran serves 51 cities, mostly in the East, from its Atlanta hub, while Frontier flies to 55 cities, mainly in the West, from its Denver base. Between Atlanta and Denver, each carrier has three daily flights.
