Allegiant Air Baggage Fees (2026)
Quick summary
Allegiant Air is an ultra-low-cost U.S. leisure carrier built around bare-bones base fares. Only a personal item is free — both the carry-on bag and every checked bag cost extra, and prices rise the closer you get to departure (cheapest at booking, most expensive at the airport). All bag charges are per bag, per segment, and the exact price depends on your route. Buying bags online when you book is almost always the cheapest option.

How to avoid extra fees
- Add every bag online at the time of booking — it is almost always the cheapest price, and waiting until the airport can more than triple the cost.
- If you can fit everything into the free personal item (8 x 14 x 18 in), you fly with zero bag fees.
- Weigh checked bags at home; staying under 50 lbs avoids the $50–$75 overweight surcharge per segment.
- Allegiant World Mastercard holders can earn priority benefits, but always compare the bag-bundle price against buying bags individually.
