Which Android app should I use for managing Allegiant flight check-in and boarding passes?

Allegiant is the official mobile application for Allegiant Travel Company, designed specifically for passengers using this low-cost airline. It consolidates key travel tasks into a single platform, allowing users to search for and book flights, select seats, check in remotely, and access digital boarding passes directly from their Android devices. This is particularly useful for frequent flyers or those with last-minute travel plans, as it enables quick adjustments and reduces reliance on physical tickets. The app also includes flight status updates and booking management features, making it a practical tool for on-the-go travel coordination. However, user feedback points to significant limitations. Reviews indicate that the app often forces users through multiple upgrade offers during check-in, even when seats are already assigned. This can create a frustrating loop where the app reverts to seat selection screens, delaying access to boarding passes. Despite these issues, the app remains functional for core operations like viewing itineraries and receiving flight alerts. For travelers prioritizing convenience with Allegiant Airlines, this app offers essential utilities, but the experience may be marred by aggressive upsells that interrupt smooth check-in workflows.
