No, Allegiant Air does not offer a traditional first-class cabin. Allegiant operates as an ultra-low-cost carrier (ULCC), focusing on providing affordable base fares with optional add-ons. Their aircraft typically have a single-class economy cabin layout, designed to maximize seating capacity and minimize costs.

However, Allegiant offers an option to purchase “Legroom+” seats, which provide extra legroom and are located in the front of the cabin or exit rows. While these seats offer more comfort than standard seats, they do not come with the enhanced services typically associated with first-class seating on other airlines, such as premium meals, lounge access, or priority boarding beyond what can be added as an extra service.
