As a passenger of Frontier, what should one typically expect regarding baggage?

The correct expectation regarding baggage when flying with Frontier Airlines is that additional fees for checked baggage are applicable. Frontier operates as an ultra-low-cost carrier, which means they offer lower base fares but charge for a variety of services that are often included in ticket prices of traditional carriers. This includes checked baggage, which generally incurs extra fees depending on the weight and the timing of the purchase (e.g., fees can be higher if paid at the airport rather than online during booking).

Frontier typically presents its ticket prices without including the cost of checked baggage to keep base fares attractive to budget travelers. Therefore, passengers should anticipate having to pay separately for checked baggage, which aligns with the airline's business model.

In contrast, the other options do not accurately reflect Frontier's policies. There are no inclusive baggage fees in the ticket price, and the baggage allowance is generally not classified as generous, as checked baggage incurs a charge rather than being free of charge. Furthermore, all baggage does not need to be carried on board, as passengers do have the option to check bags for a fee.
