Spirit Airlines is adding a new premium option for its travelers. The option will include extra legroom seating and two free checked bags for its elite members. According to the airline, the new seating will begin being installed in June and roll out across the majority of Spirit's fleet by July while the two free checked bags policy will roll out later this year. Spirit's embrace of premium options reflects a larger trend in the airline industry, and it comes after the airline exited bankruptcy in March.
