Frontier Airlines is offering a complimentary checked bag, carry-on, seat selection, and flight changes for nonstop flights booked by March 24. This promotion follows Southwest Airlines' recent announcement to end its free checked bag policy, a move that has been met with resistance from some customers.

Frontier is offering their Economy Bundle for free for nonstop flights between March 18 and August 18. They are including in the deal a free carry-on, free seat selection, and free changes, along with a free checked bag with a promo code. The airline is considering making the deal permanent.
