How online check-in works
Allegiant Air allows online check-in, which reduces wait times at the airport. Online check-in typically opens 24 hours before your departure. While exact procedures depend on your booking, the general process follows these steps:
- Visit the Allegiant Air website or mobile app.
- Enter your booking reference number and passenger name.
- Review your flight details and select your seat if applicable.
- Confirm your check-in and print or download your boarding pass.
- Arrive at the airport with your boarding pass and required travel documents.
Practical tip: Check in as early as possible (at the 24-hour mark) to secure preferred seat selections if available, as Allegiant may charge for seat selection on certain fares.
