In the realm of modern travel, online check-in has become an invaluable tool for passengers looking to streamline their travel process. The question often arises: “Why can’t I check in online for Allegiant Air?” As an expert in airlines, I’ll guide you through the intricacies of Allegiant’s check-in process.

Allegiant Air, one of the prominent budget airlines in the United States, has a unique check-in policy that differentiates it from other airlines. Unlike other carriers that allow online check-in to be a standard feature, Allegiant Air has certain restrictions and conditions that must be met.

Allegiant Air’s Check-In Policy

To understand why you might encounter issues with online check-in, we first need to understand Allegiant Air’s check-in policy. Allegiant Air, known for its cheap tickets, has specific rules for its check-in process.

Online check-in is available 24 hours before departure and closes 45 minutes prior. However, not all passengers can use the online check-in feature. If you purchased your plane tickets through Allegiant Air directly and did not opt for any additional services such as baggage or seat selection, you should be able to check in online either through the Allegiant website or the Allegiant app.

However, if you opted for extras like seat selection or baggage, online check-in becomes unavailable, and you will have to check in at the airport. The reasoning behind this policy is likely due to the way Allegiant Air structures its ancillary fees, which forms a significant portion of its revenue.

The Role of Allegiant Air Customer Service

If you’re having trouble with online check-in or any other issues, Allegiant Air customer service is there to assist. You can reach them via the Allegiant Air phone number, or alternatively, use the Allegiant customer service number. Their dedicated team is ready to help with any issues you may be experiencing, including online check-in.

While the customer service team may not be able to facilitate online check-in if you’re not eligible, they can guide you through the process and explain any queries you may have. This way, you can understand exactly what’s needed for a smooth journey.

Allegiant Air Mobile Check-In

If you’re not eligible for online check-in via the website, you might wonder if there’s another way to check-in remotely. Enter the Allegiant mobile check-in process. This is another method to check in for your flight, and it’s accessible via the Allegiant app, which is available for both Android and iOS devices.

The Allegiant mobile check-in process mirrors that of the website. You can check in 24 hours prior to your flight and up to 45 minutes before departure. Keep in mind that the same restrictions apply – if you have purchased additional services, you’ll have to check-in at the airport.

The Impact on Allegiant Airlines Reservations

The unique online check-in policy of Allegiant Airlines can impact how you plan your travel. Knowing the rules and regulations beforehand can help ensure a smooth experience when making Allegiant Airlines reservations.

When booking your airline tickets, consider whether the convenience of online check-in outweighs the benefits of additional services like seat selection or extra baggage. If online check-in is a priority for you, it might be worth forgoing these additional services during the booking process.


While Allegiant Air’s online check-in policy may seem perplexing, understanding the reasons behind it and knowing how to navigate it can make your travel experience smoother. If you’re still unsure or face issues, Allegiant Airlines customer service is always on standby to help.
