Hey,everyone! I am Marcia mark. I want to tell you about Allegiant Air Checked Baggage Policy that allows passengers to bring bags for an extra fee. The standard weight limit is 40 lbs per bag, with a maximum size of 62 inches (length + width + height). Fees vary based on route and weight, and bags can be added online for cheaper rates before your flight. To avoid extra charges, be sure to check the baggage fees and size restrictions on Allegiant's website before traveling.
