What is the fee for checking an additional bag on my Frontier Airlines flight?

Frontier Airlines allows passengers to bring one personal item and one carry-on bag on board for free. However, if you need to check an additional bag, you will be charged a fee. The cost for checking an additional bag varies depending on when and how you pay for it. If you pay for your additional bag during booking or before online check-in, the fee ranges from $35 to $60, depending on your route and travel dates.

If you decide to pay for your additional bag during online check-in, the fee increases to $40 to $65. And if you wait until you get to the airport to pay for your additional bag, the fee jumps up to $60 to $80. It's important to note that these fees are per bag, per one-way flight, and are non-refundable.

Frontier Airlines also has restrictions on the size and weight of your bags. Checked bags must not exceed 62 linear inches (length + width + height) and 50 pounds in weight. Any bags that exceed these limits will be subject to additional fees.
