Seats will be assigned at random upon check-in for these prices. You may pay a fee to choose a specific seat.
Frontier offers the Works bundle, which can be added to any flight during initial booking. It includes a standard carry-on bag plus a personal item, one free checked bag, seat selection (including stretch seating), priority boarding, flight flexibility, and refundability. This is a value if you want all of these amenities, but chances are you can get away with just adding what you need a la carte for cheaper.
