Allegiant Air is a popular ultra-low-cost airline known for its affordable, non-stop flights to leisure destinations, often serving smaller airports. When you need customer service, your primary options are their official website and telephone support. The Allegiant Air website, allegiantair.com, is an excellent first stop for managing bookings, finding FAQs, and accessing their dedicated 'Contact Us' page.

For direct assistance, Allegiant provides phone support; find the most current number on their website. Their mobile app also allows flight management and may offer in-app support. To ensure an efficient experience, always have your booking confirmation number, passenger names, and specific inquiry details readily available before contacting them. This preparation helps agents quickly assist you.

To maximize efficiency, utilize the extensive FAQ section on their website, as many common questions regarding baggage or flight changes are answered there. Be aware that phone wait times can vary, especially during peak travel. For straightforward changes like seat selection or adding baggage, managing these directly through your account on the website or app is often the quickest method.
