What Happens If You Miss Check-In

You arrive after the counter cuts off: Allegiant Air staff will refuse to issue a boarding pass for your booked flight. You will be marked a no-show, and your fare rules determine whether you get rebooked or forfeit the ticket. Allegiant Air does not offer same-day standby — expect to buy a fresh ticket.

You have a boarding pass but missed bag drop: If you already checked in online but reached the bag drop counter after 60 minutes before departure (bags accepted 1-2 hours before only) (domestic) or 60 minutes before departure (international), the agent can refuse to accept the bag. Some hubs let you gate-check a carry-on at no charge if you ditch the checked bag plan; many will not.

Doors are already closed: Boarding doors close 15 minutes before departure. Once the door is shut, the flight is released — pleading at the gate will not get you on. Your only recourse is the rebooking desk or customer service line (1-702-505-8888).

Frequently Asked Questions

What time does Allegiant Air close check-in for domestic flights?
Allegiant Air closes domestic airport check-in 45 minutes before departure. Bag drop closes 60 minutes before departure (bags accepted 1-2 hours before only). Boarding doors close 15 minutes before departure — if you are not on the jet bridge by then, you will be denied boarding even with a valid boarding pass.
Can I check a bag after online check-in?
Yes. Online check-in only confirms your seat — you still need to drop bags at a Allegiant Air bag drop counter before the cutoff. Allegiant Air's bag drop closes 60 minutes before departure (bags accepted 1-2 hours before only) for domestic and 60 minutes before departure for international. Arrive earlier than the bag drop deadline because the line itself can take 15–30 minutes at busy hubs.
What happens if I miss Allegiant Air's check-in cutoff?
If you miss Allegiant Air's check-in cutoff, you will be denied boarding and Allegiant Air does not offer same-day standby. You will need to purchase a new ticket — Allegiant Air fares are non-refundable.
Does Allegiant Air have a minimum connection time for bags?
Allegiant Air's standard minimum connection time for checked bags on a same-airline same-airport connection is approximately 30 minutes — though this varies by airport and is set by the airport authority, not the airline. International-to-domestic connections requiring re-clearing customs typically need 60–90 minutes. Always verify the official MCT for your specific connection.
