By fare / bag product
What you can bring often depends on the ticket—not only the airline name. Re-check Allegiant Air's baggage page (last checked 2026-08-30).
| Fare / product | Carry-on / cabin bag | Personal / small bag |
|---|---|---|
| Basic / lowest fare | Not included on this fare (small bag only) | 18 × 14 × 8 in |
| bundle | 22 × 16 × 10 in | 18 × 14 × 8 in |
- Basic / lowest fare: Allegiant: every passenger gets one free personal item (max 8×14×18 in / 20×35×45 cm) under the seat in front. Carry-on and checked bags are optional paid add-ons—reserve via Manage Travel before travel; airport prices are higher. Oversized personal items and oversized/excess carry-on incur airport bag fees. Checked (when purchased): up to 4 bags per passenger, each max 50 lb (22 kg) and 80 linear in (203 cm) height+width+length including wheels and handles; extra charges for over 50 lb, sports gear, oversize/excess.
- bundle: Use this row when your fare or bundle includes one purchased carry-on. Carry-on max 10×16×22 in (25×40×55 cm), overhead bin. Same free personal item (8×14×18 in) and same checked limits as basic when prepaid: up to 4 checked bags per passenger, 50 lb and 80 linear inches each including wheels/handles; reserve early for lower fees.
Airline-specific notes
- Checked linear limit is higher than the common 62 in benchmark.
- Airport staff may enforce dimensions in alternate orderings.
- Allegiant baggage-1 / terms: personal 8×14×18 in; carry-on 10×16×22 in; checked 80 linear in / 50 lb. Rechecked 2026-08-30 (ignore older 7×15×16 popup wording).
How Airlines Calculate Luggage Size
Airline baggage limits in inches are based on the outer box dimensions of your bag, not volume.
- Carry-on rule (most common): single-side limits such as 22 x 14 x 9 in (L x W x H).
- What must be included: wheels, handles, feet, and any rigid external parts.
- What is not used as the main rule: liters/cubic volume is usually not the acceptance criterion.
- Sizer logic at airport: if the bag does not fit the frame, it can be denied or gate-checked.
