Passengers traveling on the airline, which does not serve any of the Washington area's three major airports, will start having to pay $35 for a carry-on bag. Purses, backpacks and laptops will still be free.
However, Airline Reporter says that fees will be discounted if you book travel through the airline's website.
Allegiant will become the second domestic carrier to charge for carry-on bags. The other, Spirit Airlines, charges $30 for a carry-on bag.
The airline's website already lists various, "optional" fees for travel, including seat assignment, priority boarding and other services.
