Here’s what we could confirm about Allegiant Air bags as of 2026-10-31. Your fare, route, ticket date, benefits, and the airline flying the trip can still change the answer.
Check my flight and bags
What we know: Some rules checked
If you don’t see a price here, it doesn’t mean the bag is free. Check the final charge and acceptance rules with Allegiant Air for your flight.
When these rules apply
Allegiant ordinary baggage; route and purchase channel determine prices.
Checked, carry-on and personal item limits
Start with these published limits, then check the fare you bought. Measure the packed bag on the outside, including wheels and handles.
| Policy detail | Value |
|---|---|
| Standard checked weight (lb) | 50 |
| Standard checked size (linear in) | 80 |
| Personal item (in) | 18 × 14 × 8 |
| Carry-on (in) | 22 × 16 × 10 |
| Prepurchase max pieces | 4 |
Checked bags, extra pieces and excess fees
- No single base fee imported. Standard checked dimensions allow 80 linear inches, not a generic 62.
These prices apply only to the conditions listed above. Your route, fare, ticket date, or benefits can change what you pay.
How to add and pay for bags
- Choose cabin or checked product deliberately.
- Confirm the route quote and allowed pieces.
- Retain purchase confirmation.
Do not assume 62 linear inches is the standard checked size.
Free bags and possible savings
- Use the included personal item correctly and purchase only the cabin/checked products needed.
Special items, connections and refunds
We couldn’t confirm one Allegiant Air price that covers every sports item, stroller, or mobility device. Ask about the exact item you’re bringing, especially if another airline flies part of the trip. If a paid checked bag is delayed or lost, report it to the airline and keep the bag tag and fee receipt.
- Special equipment, heavy bags and assistive devices need their applicable policy, not generic bag pricing.
Questions to answer before you pay
Does every airline use 62 inches for checked bags?
No. Allegiant’s ordinary checked limit is 80 linear inches; JAL’s stated international allowance is 203 cm.
Next: Load the airline’s actual limit rather than a generic default.
Does prepaying a bag complete airport check-in?
No. Purchasing a baggage allowance and physically checking in or dropping the bag are different actions.
Next: Follow the airline’s separate check-in and bag-drop deadlines.
Cabin item decision
| Item | Researched outside dimensions |
|---|---|
| Personal item | 18 × 14 × 8 in |
| Carry-on | 22 × 16 × 10 in |
Allegiant lists one free underseat personal item; a carry-on is a separate paid product unless included through another purchase. A dimensions check tells you whether the bag fits the researched box; it does not determine fare inclusion, cabin space or the gate agent’s final acceptance. Open the official cabin-bag policy.

Checked bags
This page covers Allegiant ordinary baggage; route and purchase channel determine prices.. The standard weight listed here is 50 lb. Check the purchased fare for the included piece count.
Carry-on
The official cabin source lists 22 × 16 × 10 inches for the outside box. Fare inclusion and aircraft space are different questions from size.
Personal item
The official cabin source lists 18 × 14 × 8 inches for the underseat box. The item still needs to fit under the seat on the operating flight.
Overweight fees
The standard weight listed here is 50 lb. A heavier bag may cost extra. Check the base bag price and the excess charge together before you pay.
Oversized fees
The standard outside-size limit listed here is 80 linear in. Measure outside length, width and height and separately check the maximum accepted size.
Extra bag numbers
Your second or third bag may cost more than your first. Start with the bags included on your ticket, then price each additional piece for that traveler.
Fare baggage allowance
Allegiant Air allowance cannot be inferred from the brand alone. Match the fare printed on the ticket, the route, any bundle and the date the ticket was issued or changed.
Add or pay for bags
Choose cabin or checked product deliberately. Confirm the route quote and allowed pieces.
Free checked bags
Use the included personal item correctly and purchase only the cabin/checked products needed. A standard-piece waiver does not automatically waive excess weight or size.
Sports equipment
Bringing a bike, golf bag, skis, or an instrument? Check the airline’s packing and special-item rules before using an ordinary checked-bag price.
Family and medical bags
A stroller, car seat, or mobility device may follow different rules from a suitcase. Tell the airline what you’re bringing and check its handling and battery instructions.
Connecting flights
Check whether each segment is marketed and operated by Allegiant Air or a partner. A separate ticket can require a new bag purchase and physical recheck.
Baggage refunds
If a paid checked bag is lost or significantly delayed, report it to the airline and keep your bag tag and fee receipt. An unused prepaid bag has a different refund question.
For any unresolved detail, check the Allegiant Air policy for the current ticket and operating flight.
