Are you flying Allegiant Air anytime soon? Then it's time to talk about something that surprises many budget-conscious travelers off guard: their carry-on size requirements. Unlike legacy carriers that throw in free baggage, Allegiant operates on an ultra-low-cost model where every bag counts and that includes what you bring onboard. Understanding Allegiant Air carry-on size restrictions can save you significant fees and hassle at the airport. So, read our blog on Allegiant air carry on size and everything you need to know for hassle-free travel.
Wondering what is the carry-on size for Allegiant? Well, the airline allows maximum dimensions of 22 x 16 x 10 inches (55 x 40 x 25 cm), with measurements including handles, wheels, and any decorative elements. You'll need to purchase Allegiant airlines carry-on size baggage separately, whether during booking, pre-departure, or at the airport.
The cost difference is significant. Pre-purchasing during initial booking costs $18–$25, but wait until the airport and you'll pay $50. That alone should motivate you to plan ahead.
This is where travelers commonly slip up. Personal item Allegiant carry-on size is completely different from your carry-on bag. Allegiant includes one free personal item measuring 8 x 14 x 18 inches maximum. The personal item is your purse, small backpack, briefcase, or laptop bag. It must fit completely under the seat in front of you.
Here's the honest answer: how strict is Allegiant with carry-on size depends on the gate agent you encounter. Some travelers report bags getting through without measurement, while others face the dreaded sizer box at check-in or the gate. The safest approach? Pack within the stated dimensions exactly. Soft-sided bags work in your favor since they're compressible—meaning you might squeeze an oversized bag into compliance if it's not rigidly packed.
That said, personal item Allegiant carry-on size enforcement appears more consistent than carry-on measurements, so don't risk pushing your personal item beyond limits.
Beyond your personal item, you're allowed several items at no extra cost. You can bring one coat or jacket, one small umbrella, food for onboard consumption, a diaper bag, and one item of reading material. Medical devices like CPAP machines, crutches, and wheelchairs also don't count toward your baggage limits. Parents traveling with infants can gate-check one stroller and one car seat free of charge.
Since Allegiant doesn't offer in-flight entertainment, Wi-Fi, or complimentary snacks, pack your personal item wisely. Load entertainment, snacks, and essentials into that free personal item, keeping it accessible under your seat throughout the flight.
For your purchased carry-on bag, remember there's no weight limit; only size restrictions. This means you can pack heavier items if you stay within dimensions, unlike airlines that enforce both size and weight restrictions.
While there's no specified weight limit for Allegiant carry-on size requirements, checked bags have weight limits. Each checked bag can weigh 50 pounds max. If your bag exceeds this weight limit then the extra fees incur at 51–70 pounds ($50) and 71–100 pounds ($75). Since your carry-on weighs less when traveling light, you're somewhat protected here.
Flying Allegiant Air doesn't have to be stressful if you know the rules upfront. The key takeaway? Your Allegiant air carry-on size of 22 x 16 x 10 inches is mandatory, and knowing this prevents costly gate surprises.
