If you need help with an Allegiant reservation, flight change, cancellation, refund, baggage issue, or upcoming trip, the fastest response usually comes from using the support channel that matches your problem.
Official Allegiant Air Customer Service: +1-702-505-8888
Alternative / Third-Party Travel Assistance: +1-833-319-4929
+1-833-319-4929 is an alternative third-party travel-assistance number and is not Allegiant Air's official customer-service or reservation number.
What Is the Allegiant Air Phone Number?
The official Allegiant Air Reservations Center and Customer Care number is +1-702-505-8888.
This number can be used for reservations, existing bookings, customer-care enquiries, and other travel-related issues.
Before calling, keep these details ready:
- Passenger name
- Allegiant confirmation number
- Flight date
- Departure airport
- Destination
- Email used for the booking
- Exact change or problem you need resolved
1. Call Allegiant Customer Service for Urgent Problems
For an urgent problem, call Allegiant Air customer service at +1-702-505-8888.
Calling is usually the better option when your flight is approaching and the problem cannot be resolved online.
Examples include:
- Flight departing soon
- Reservation cannot be accessed
- Complex booking change
- Special assistance request
- Schedule-change problem
- Cancellation issue
- Account or payment problem
2. Use Manage Travel Before Calling
For normal booking changes or cancellations, try Manage Travel first.
Allegiant's online booking tools can help with common tasks without waiting for a customer-service agent.
You may be able to:
- Change flight dates
- Update seats
- Add checked baggage
- Add carry-on baggage
- Upgrade certain trip options
- Cancel an eligible itinerary
If Manage Travel does not resolve the problem, call customer service and explain exactly what happened online.
3. Use Live Chat for Quick Questions
Allegiant also provides Live Chat through its customer-support channels.
Chat may be useful when your issue does not require immediate airport intervention or a complicated ticket change.
Live Chat can help with:
- General booking questions
- Baggage-policy questions
- Seat questions
- Account guidance
- Clarifying an online booking process
4. Contact Allegiant Before the Problem Becomes Urgent
If you already know you need to change or cancel your booking, do not wait until you arrive at the airport.
Open Manage Travel first and review the available change or cancellation options.
If your flight is approaching and you need personal assistance, call 702-505-8888 as early as possible.
5. Use the Right Number for Baggage Problems
If your problem is specifically baggage-related, use the baggage support number instead of starting with general reservations.
Baggage Service Office / Lost & Found: 866-719-3910
This number can be useful for:
- Missing baggage
- Delayed baggage
- Damaged baggage
- Lost items
- Baggage claim follow-up
6. Check Flight Status Before Calling About a Delay
Check your flight status first if the problem involves a delay or schedule change.
Once you know the updated departure time, you can ask customer service a more specific question about available rebooking, cancellation, or travel options.
For example:
Instead of saying, "Is my flight delayed?" you can say, "My flight has moved from 4:00 PM to 8:30 PM. What rebooking options are available on my reservation?"
7. Use Customer Relations for Past-Trip Problems
If your trip is already completed, written Customer Relations may be more appropriate than calling reservations.
Allegiant lists the following Customer Relations mailing address:
Allegiant Travel Company
ATTN: Customer Relations Department
PO Box 371730
Las Vegas, NV 89137
United States
This channel is better suited to post-travel feedback and complaints than to urgent same-day travel issues.
