Frequently asked questions
What is the Allegiant carry-on size limit?
Allegiant Air’s own baggage page gives the carry-on limit as 22 x 16 x 10 in / 55 x 40 x 25 cm. Must fit in the overhead bin. Measure the bag with wheels and handles, standing up, and compare the longest side with the longest limit.
Does Allegiant weigh carry-on bags?
The Allegiant page read for this site states no carry-on weight limit. That does not mean any weight is fine: you must be able to lift the bag into the overhead bin yourself, and gate agents can still check a bag that does not fit.
Will a 22 x 14 x 9 inch bag fit Allegiant?
Yes. A bag measuring exactly 22 x 14 x 9 inches with wheels meets Allegiant’s published carry-on limit, with 0 in to spare on its tightest side. Bags whose listed size excludes wheels are often an inch or two longer in reality, so check the wheels-included figure.
Is the Allegiant carry-on included in the fare?
On the page read for this site, the carry-on is fare-dependent (check your fare rules). Basic or light fares at some airlines restrict the overhead bag, so confirm what your specific ticket includes before you pack.
Researched, not professional advice. Airline limits change without notice and can differ by route, aircraft and fare; the airline's own page is the final word.
