Hi everyone! I’m Giantakeshi. Many people Can you choose seats on Allegiant Air? The answer is yes! You can pick your seat, but it will cost a bit more. Prices start at $1 for a middle seat and can go up to around $37 for a seat with extra legroom. This is perfect if you want to be comfortable or sit with friends. If you don’t want to pay for a seat, Allegiant will give you one at check-in, but you might not be next to your travel buddies. Choosing your seat early can make your trip easier and more fun.
