What is Allegiant Air's checked bag weight and size limit?
Every bag on Allegiant Air must weigh 50 lbs / 23 kg or less and measure no more than 62 linear inches (length + width + height) to avoid surcharges. Both limits apply independently — a light bag that is too large still triggers the oversize fee.
| Fare | 1st bag | 2nd bag |
|---|---|---|
| Main cabin | Varies by route; use allegiantair.com baggage calculator (no published flat fee) | Varies by route; up to 4 checked bags allowed per passenger |
| Basic economy | Varies by route; use allegiantair.com baggage calculator (fully a-la-carte model) | Varies by route; up to 4 checked bags allowed per passenger |
Fees shown are for online pre-payment where applicable. Paying at the airport counter or gate typically runs higher.

How do bag fees affect my Leave-By Time?
Checking a bag adds 20–30 minutes to your airport buffer compared to carry-on only. You need time to join the bag-drop queue, hand off the bag, and collect your receipt before you can head to the TSA checkpoint. That window sits before security — not inside it — so it shifts your Leave-By Time at home earlier, not just your airport arrival.
Use the Leave-By Time calculator — enter your flight, mark that you are checking a bag, and the calculator adds the bag-drop counter step so you leave home with exact numbers instead of a rough guess.
Things to know before you check a bag on Allegiant Air
