Choosing the right option depends on whether you’re checking baggage, traveling internationally where applicable, requiring special assistance, or simply preferring digital travel documents.

Online check-in is the preferred option for most passengers because it reduces waiting time and lets you arrive at the airport with your boarding pass already available.
Follow these simple steps:
- Visit the airline’s official website.

Completing these steps before arriving at the airport often results in a smoother travel experience, especially during busy holiday seasons.

Travelers who prefer using smartphones can complete the check-in process and store a digital boarding pass for convenient access at the airport.
Mobile check-in is especially useful because passengers can:
- Access boarding passes instantly.
- Reduce paper usage.
- Receive travel notifications.

Before leaving for the airport, ensure your phone is fully charged and consider taking a screenshot of your boarding pass in case your internet connection becomes unreliable.
Airport Check-In
Airport check-in remains a practical option for travelers who could not complete online check-in or who require additional assistance.
Upon arriving at the airport:

- Present a valid government-issued photo ID.
- Verify your reservation.
- Check any luggage if needed.

Many airports offer self-service kiosks that provide a faster alternative to waiting at a staffed counter.
Using a kiosk generally involves:
- Scanning identification or entering your confirmation details.
- Reviewing your itinerary.
- Printing your boarding pass.
- Printing baggage tags when applicable.
- Proceeding to the baggage drop counter if checking luggage.
Kiosks combine the convenience of online check-in with the flexibility of completing the process at the airport, making them a popular choice for travelers who arrive early but have not checked in beforehand.
Allegiant Check-In Time and Important Deadlines
Knowing the check-in timeline is just as important as knowing how to check in. Missing the airline’s check-in or baggage deadlines could result in being denied boarding, even if you arrive before your flight departs.
As a general rule, complete your online check-in as soon as it becomes available. If you plan to check baggage, allow extra time to drop off your luggage before heading through airport security.
Recommended Airport Arrival Times
| Travel Situation | Recommended Arrival Time |
|---|---|
| Carry-on baggage only | At least 2 hours before departure |
| Checking luggage | At least 2–3 hours before departure |
| Traveling during holidays | At least 3 hours before departure |
| First-time flyer | At least 3 hours before departure |
| Travelers needing special assistance | At least 3 hours before departure |
Arriving early gives you enough time for parking, baggage drop, security screening, finding your gate, and handling unexpected delays.

A mobile boarding pass can be stored on your smartphone for quick access.
Benefits include:

Many experienced travelers keep both digital and printed versions for added peace of mind.
Checking Bags After Online Check-In

Understanding your baggage type can save valuable time.
| Carry-On Bag | Checked Bag |
|---|---|
| Travels with you | Stored in aircraft cargo hold |
| No baggage drop required | Must be checked before security |
