Author : FareHub Desk USA Support | Published On : 31 Mar 2026
Understanding Allegiant Air baggage weight rules is essential if you want to avoid surprise fees at the airport. Allegiant operates on an à‑la‑carte model—meaning you pay only for what you bring. This makes knowing the limits for personal items, carry‑ons, and checked bags more important than ever.
Below is a clear, people‑first guide designed to help you pack confidently while meeting Allegiant’s requirements.
What Is the Checked Baggage Weight Limit on Allegiant Air?
Allegiant allows passengers to pre‑purchase up to four checked bags, each with a maximum weight of 50 pounds (22 kg). Exceeding this limit triggers additional fees, and bags over 70 pounds may incur even higher charges.
Key checked‑bag rules:
- Standard weight limit: 50 lbs (22 kg)
- Oversized/overweight fees apply for:
- 51–70 lbs
- 71–100 lbs
- Maximum size: 80 linear inches (203 cm)
These limits help Allegiant maintain safety and efficiency, and they’re strictly enforced.
Carry‑On & Personal Item Weight Rules
Allegiant includes one free personal item with every ticket. This must fit under the seat and follow size guidelines, but there is no published weight limit—as long as you can stow it yourself.
If you want overhead space, you’ll need to purchase a carry‑on bag. While Allegiant does not list a strict carry‑on weight limit on its main policy page, the bag must be easy for you to lift and place in the bin.
Carry‑on size limit: 10 x 16 x 22 inches (25 x 40 x 55 cm)
Tips to Avoid Overweight Bag Fees
- Weigh your luggage at home—even a few extra pounds can cost you.
- Pre‑purchase bags online; airport prices are significantly higher.
- Measure wheels and handles, as Allegiant counts them in total size.
- Pack strategically to stay under the 50‑lb checked‑bag threshold.
