What Will Happen If You Show Up With An Oversized Carry-on ?

It is always advisable to know the exact suitcase size before you use it on your flight.

Overall a slightly oversized bag can can get on abroad the airplane, if you come across a lenient and nice airline clerk.

If you are carrying with a way too large carry-on bag, I don’t think it gonna make it as a carry-on, even if you are ready to pay for it.

It will get gate checked.

Because it will not fit in either the overhead compartment or under the seat in front of you, and it may obstruct the movement in case of an emergency case.

But if you are planning to take the risk anyways it is better to use a soft sided bag, because it can be squeezed easily in the luggage sizer at the airport, in the overhead compartment or under the seat in front of you.

Does Allegiant Check Carry-on Bags?

Allegiant Air has baggage sizers at the airport, so most of the time you will be required to place your suitcase on it.

You won’t have any problem if it is slightly bigger, but if it is too large you will be required to check in your bag.
