If you’ve ever experienced an Allegiant Airlines missed flight, you know how stressful and costly it can be. Allegiant, being a low-cost carrier, operates with strict schedules and limited flexibility when it comes to flight changes or rebooking options. That’s why it’s crucial to understand how early you need to arrive at the airport to avoid missing your flight. Unlike major carriers that may offer more frequent departures or more generous rebooking policies, Allegiant usually flies certain routes only a few times per week—so a missed flight can derail your entire trip.
In this guide, we’ll explain Allegiant Airlines’ timing policies, provide expert arrival recommendations, and share essential tips to help you fly stress-free.
Allegiant Airlines: Why Arriving Early Matters More
Allegiant operates on a streamlined, low-cost model. That means:
-
Fewer daily flights on each route
-
Limited airport staff at smaller terminals
-
Strict check-in and boarding deadlines
With these factors in mind, there’s little room for error. If you’re late, there’s a good chance you’ll be left behind—and you may have to purchase a new ticket entirely.
Why Arriving Early Is Essential with Allegiant Airlines
Allegiant Airlines operates many flights out of smaller, regional airports with fewer staff and limited flights per day. Because of this, missing a flight can mean waiting days for the next available one or paying for a new ticket altogether. Plus, Allegiant has strict check-in deadlines:
-
Check-in counters close 45 minutes before departure
-
Boarding gates close 15 minutes before departure
Failing to meet these cutoffs can result in losing your seat without a refund or free rebooking. Therefore, it’s critical to allow plenty of time for check-in, baggage drop, security screening, and reaching your gate.
Recommended Arrival Times for Allegiant Flights
1. Domestic Flights: Arrive at Least 2 Hours Early
Allegiant Airlines recommends arriving a full 2 hours before departure for all domestic flights. This allows enough time for:
-
Ticket counter check-in (if you haven’t done it online)
-
Baggage drop-off
-
Security screening
-
Getting to your departure gate
Important: Allegiant’s check-in counters close 45 minutes before the scheduled flight time, and boarding gates close 15 minutes before departure. Arriving even a few minutes late can cost you your flight.
2. If You Checked In Online: Still Arrive Early
Even if you’ve checked in online and have no bags to check, TSA wait times and airport layout can still delay you. Aim to be at the airport at least 90 minutes prior—even with a mobile boarding pass in hand.
3. Traveling During Peak Times: Add Extra Buffer
During holidays, weekends, or early morning hours, lines can be unpredictable. In such cases, arriving 2.5 to 3 hours before departure is a safe bet.
Key Allegiant Timing Rules to Remember

Check-in counter closes: 45 minutes before departure
