Sports Equipment
Each piece of sporting equipment is considered a checked bag with applicable fees. Additional charges apply for overweight or oversized equipment.
Musical Instruments
Small instruments allowed as carry-on if they fit in overhead bin or under seat. Instruments weighing 165 lbs or less will not incur an excess weight fee.

Tips to Avoid Fees
1. Pay for bags during initial booking to avoid higher airport fees. 2. Travel with only a personal item that fits under the seat. 3. Active military personnel can get free bags through Allegiant Honors. 4. Buy tickets at the airport counter to avoid the $22 per segment electronic usage charge.
Unique Nuances
Allegiant charges baggage fees per segment (per takeoff and landing). Active duty military personnel receive up to 2 free checked bags, 1 free carry-on, and 1 free personal item through the Allegiant Honors program.
