Missed Your Flight? Here’s What to Do
Missing a Allegiant Airlines flight can ruin your day. But there are a few steps you can take if it happens with Allegiant.
Understand Allegiant’s Missed Flight Policy
Allegiant has strict rules. They don’t allow free changes or same-day rebooking for missed flights. In most cases, if you miss your flight, your ticket is no longer valid.
But that doesn’t mean you’re out of luck.
Step 1: Call Customer Service
If you know you’ll be late, call right away. Sometimes, if you act quickly, the airline may help rebook you. This depends on the situation and availability.
Step 2: Use Trip Flex (If You Bought It)
Trip Flex is an option you can add when booking. It allows you to change your flight once without a change fee. You’ll still need to pay any difference in fares.
With Trip Flex, you must change your booking at least 1 hour before the flight.
Step 3: Look for the Next Flight
If there’s another Allegiant flight that day or the next, you may be able to buy a new ticket. Allegiant doesn’t offer same-day standby, but they may offer a discounted rebooking fee.
Step 4: No-Shows Get No Refund
If you miss your flight and don’t call, your booking is cancelled. You won’t get a refund or flight credit.
That’s why it’s important to stay in touch with Allegiant if your plans change.
Avoid Missing a Flight
It’s always better to plan ahead. Here are a few tips to help you get to the airport on time:
Arrive 2 hours before departure
Check in online 24 hours before your flight
Set travel reminders on your phone
Keep travel documents ready
Watch your email and text messages for updates
Changing or Managing a Booking
If you need to make changes after booking, use the “Manage Travel” section on the website. You can:
Change flight dates
Add bags or seats
Buy extras like hotel stays or rental cars
Reprint your boarding pass
You’ll need your name and confirmation number to log in.
Baggage Rules: What’s Included?
Allegiant Airlines keeps costs low by only including a personal item in the basic fare. This is usually a small bag like a purse or backpack.
You must pay extra if you want:
A carry-on bag
A checked suitcase
Buying baggage at the time of booking is cheaper than doing it at the airport. If you wait, the fees go up.
Check-In Options
There are three ways to check in:
Online – This opens 24 hours before departure. It’s the fastest and easiest.
Mobile App – You can check in and download your boarding pass.
Airport Kiosk – If you prefer, you can check in at the airport.
Online check-in saves time. It also helps avoid queues at the airport.
Seat Selection
You can pick your seat during booking. If you skip this step, a seat will be assigned at check-in. Some people like to pay extra for a window seat or one near the front.
If you’re travelling with family, it’s best to select seats early to make sure you sit together.
Allegiant Credit Vouchers
If you cancel a flight (with or without Trip Flex), you may receive a voucher for future travel. These vouchers are valid for one year. You can use them for flights, baggage, or extras.
Be sure to keep the voucher code safe. You’ll need it when booking your next trip.
