Most of these deals sell out quickly so it is essential to make sure you sign up for email alerts and purchase tickets asap!
If you plan to do a Frontier check in which includes luggage, then you can purchase your luggage online prior to your flight and then check in at the Frontier Airlines counter and pay the luggage fees.
This airline charges between $10-$20 to select each seat, so I skipped this step when I was purchasing our tickets.
You will be charged $30 to take carry-on luggage on board (less than 35 pounds) and $25 to check in luggage. If your bag is bigger than a personal item bag, then you be charged $60 at the gate when flying Frontier Airlines.
