Frontier Airlines Baggage Policy offers transparency and flexibility for low-cost travelers. Passengers may bring one personal item free, such as a purse or laptop bag. Additional luggage, including carry-ons and checked bags, require a fee. Costs vary based on travel dates, baggage weight, and purchase timing. To save, add baggage during initial booking. Checked bags should weigh under 40 lbs and meet size limits. Frontier enforces policies strictly at the gate, often charging higher fees for last-minute purchases. Review their baggage calculator online before flying. Smart packing and early baggage selection can ensure a smooth and affordable travel experience.
