Check my bag for Allegiant AirThe three baggage types, explained
Airlines split what you travel with into three allowances. Each has its own size and weight limit, and the one you exceed decides what you pay.
The small bag that goes under the seat in front of you — handbag, laptop bag or small backpack. Usually free and rarely weighed.
The wheeled case you take into the cabin and store in the overhead bin. Sized at the gate, and weighed by many airlines.
The large suitcase you hand over at the desk and collect at your destination. Charged by bag, with strict weight limits.
Frequently Asked Questions
Is a cabin bag free on Allegiant Air?
Not on every fare. The cheapest option (Standard fare) includes only a small bag up to 18 × 14 × 8 in (45 × 35 × 20 cm) that fits under the seat. A cabin bag up to 22 × 16 × 10 in (55 × 40 × 25 cm) comes with Paid carry-on add-on.
What happens if my bag doesn't fit Allegiant Air's sizer?
Staff can send it to the hold at the gate and charge for it, and a gate charge is usually far more than adding the bag online before you fly. The current amounts are on Allegiant Air's own fees page. Allegiant Air baggage fees
