Booking a flight with Allegiant Airlines can be a seamless experience when done correctly. As one of the leading ultra-low-cost carriers in the United States, Allegiant offers affordable fares to numerous destinations. In this comprehensive guide, we walk you through every detail of the Allegiant Airlines flight booking process, including useful tips, requirements, and insider advice to ensure you secure the best possible deal.
Allegiant Airlines operates differently from traditional airlines. The airline focuses on low-cost, nonstop travel between smaller cities and popular vacation destinations. Allegiant’s model is built on offering base fares at very low prices, with optional add-ons for baggage, seat selection, and priority boarding. By understanding this structure, travelers can plan efficiently and avoid unnecessary fees.
When you book through Allegiant’s official website or mobile app, you gain access to exclusive deals, bundle options, and flight management tools that make travel planning simple and cost-effective.
Begin by visiting www.allegiantair.com — the official Allegiant Airlines booking portal. This is the most secure and direct way to purchase your ticket, ensuring transparency in pricing and access to real-time flight availability.
On the homepage, you’ll see the flight search box, where you can enter your:
Departure and destination cities
Travel dates
Number of passengers
Select either a one-way or round-trip option based on your travel preference. Allegiant also provides options to book flight + hotel packages for vacation travelers.
Once your basic information is entered, click “Search” to proceed. The site will display available flights based on your input. You’ll be able to view:
Flight times
Duration of each flight
Available fare types
Allegiant typically operates limited flights per week on certain routes, so flexibility with your travel dates can result in significant savings. Always compare fares across nearby days to identify the best price.
After reviewing the flight options, choose the one that aligns with your travel schedule and budget. Allegiant offers different fare bundles, such as:
Standard Fare: Basic seat with no extras
Allegiant Bundle: Includes priority boarding, checked bag, and seat selection
Trip Flex Option: Provides flexibility to modify your travel plans without high change fees
If your itinerary might change, consider opting for Trip Flex, which gives you peace of mind by allowing one-time flight modifications.
Allegiant’s unique business model allows passengers to customize their trip with optional add-ons. This step is crucial for ensuring comfort while keeping costs under control.
You’ll have the opportunity to:
Select your seat: Choose from standard, extra legroom, or premium seats.
Add baggage: Pre-purchase checked bags and carry-ons for a lower rate than at the airport.
Upgrade services: Include priority boarding, rental cars, or hotel accommodations.
Pro tip: Purchasing add-ons online while booking is often cheaper than adding them later.
Before proceeding to payment, double-check that all passenger names, travel dates, and flight numbers are accurate. Allegiant requires that names match the government-issued ID exactly. Any discrepancy may lead to check-in issues or denied boarding.
You can also add special service requests, such as wheelchair assistance or traveling with pets, during this stage.
Allegiant accepts major credit and debit cards for payment. Review your total fare, including all taxes and optional services, before confirming. Once payment is submitted, you’ll receive a confirmation email containing your booking reference number and flight itinerary.
Keep this email handy, as it will be required for check-in and any future modifications.
After booking, you can manage your reservation directly through “Manage Travel” on the Allegiant website. Simply enter your confirmation number and last name to:
View or modify your booking
Add bags or seat selections
Change flight dates (if eligible with Trip Flex)
Print your boarding pass
Allegiant also offers a mobile app, available for iOS and Android users, where you can access boarding passes, receive updates, and manage travel plans seamlessly.
Online check-in is available starting 24 hours before departure and closes 45 minutes prior to takeoff. It’s recommended to complete this process early to avoid long lines at the airport.
To check in online:
Visit Allegiant’s check-in page or open the mobile app.
Enter your confirmation details.
Review your flight information and select your boarding option.
Print your boarding pass or save a digital copy on your phone.
Note: Allegiant charges a boarding pass printing fee at the airport, so using mobile or printed passes in advance is cost-effective.
To maximize your savings and enjoy a smooth booking experience, follow these proven strategies:
Allegiant operates on a limited schedule, and fares tend to rise as departure dates approach. Booking at least two to three months in advance often yields the lowest fares.
By signing up for promotional emails, you’ll receive notifications of flash sales, discounted vacation packages, and exclusive promo codes.
Allegiant often serves smaller regional airports, which can offer lower fares and faster check-in experiences compared to major hubs.
Avoid unnecessary baggage fees by packing efficiently. Allegiant’s base fare includes one personal item, such as a small backpack or purse, at no extra charge.
Frequent travelers can earn points on every purchase, redeemable for flights, hotels, and vacation packages.
Before confirming your reservation, it’s essential to familiarize yourself with Allegiant’s travel policies to avoid unexpected costs.
Allegiant allows free cancellation within 24 hours of booking, provided the flight is at least seven days away. After this period, standard cancellation fees apply unless you purchased Trip Flex.
Without Trip Flex, flight changes are subject to fees and fare differences. With Trip Flex, you can modify your itinerary once without incurring additional charges.
Personal Item: Free (must fit under the seat).
Carry-On Bag: Fee varies by route and booking time.
Checked Bags: Fees depend on weight and number of bags.
Prepaying online always saves money compared to paying at the airport.
While third-party sites may advertise Allegiant flights, booking directly through Allegiant’s website or app ensures:
Access to the lowest fares
Full control over trip modifications
Immediate customer support for any issues
Eligibility for Trip Flex and bundle deals
In addition, Allegiant’s direct booking platform provides transparent pricing without hidden fees.

Having your confirmation number ready when contacting the support team will help expedite the process.
