Allegiant Air's main customer phone number is 702-505-8888

That number connects you to Allegiant's reservations and customer service team. Wait times vary by time of day and season — mornings and weekdays are usually shorter than evenings and weekends. The line is open seven days a week, though hours may shift during holidays.

Allegiant also operates a separate number for passengers already at the airport: 702-505-8888 (the same line routes you based on your situation). If you are calling about a flight that departs within 24 hours, have your confirmation number ready — it speeds up the process.

The airline does not charge a fee to call customer service, but standard phone rates explore if you are calling from outside the United States. International callers should expect higher costs depending on their carrier.

Key Takeaways

  • Allegiant's main customer service number is 702-505-8888, available seven days a week for reservations and general questions.
  • Have your confirmation number or booking reference ready before calling, as it helps the representative locate your reservation faster.
  • Call during off-peak hours (early morning or mid-week) if you want shorter wait times.
  • Allegiant also offers support through its website chat feature and social media accounts for questions that do not require when ready phone contact.

What you can handle by phone versus online

Some tasks are faster online. Checking your flight status, changing your seat, adding baggage, or viewing your itinerary all work through Allegiant's website or mobile app without waiting on hold. You can also print or read your boarding pass online up to 24 hours before departure.

Call the phone line when you need to make changes that the website will not let you complete — canceling a flight, requesting a refund, disputing a charge, or dealing with a missed connection. You also need to call if you have a disability accommodation request, need to add a lap infant to your booking, or want to discuss a special circumstance like bereavement fares.

Alternative ways to contact Allegiant

Allegiant's website includes a chat feature during business hours. The chat is often faster than the phone line during peak times, though it may not be available late at night or very early in the morning. You can access it from the "Contact Us" page on Allegiant's website.

The airline also monitors its social media accounts on Facebook and Twitter. Messaging Allegiant directly on these platforms can work for non-urgent questions, though response times are slower than the phone line — usually several hours to a full day.

For written correspondence, Allegiant accepts mail at its Las Vegas headquarters, but this is the slowest option and should only be used for formal complaints or documentation you need in writing. The address is available on the airline's website under "Contact Us."

What to expect when you call

After you dial, you will hear an automated menu asking why you are calling. Listen to the options and select the one closest to your reason — this routes you to the right department and can shorten your wait. If you are unsure, selecting "reservations" usually works because that team can transfer you if needed.

Wait times range from a few minutes to over an hour during busy periods. Allegiant does not offer callback options, so you will stay on the line. Have your confirmation number, booking reference, or ticket number ready. If you are calling about baggage, a refund, or a complaint, also have any relevant receipts or documentation nearby.

The representative will ask for your name and confirmation number to pull up your reservation. Be clear about what you need — whether it is a change, cancellation, refund, or information about a specific flight. If the first representative cannot help, they can transfer you to a specialist.

Reaching Allegiant for specific situations

Missed flight or missed connection: Call when ready. Allegiant may rebook you on the next available flight at no charge if the delay was the airline's fault, but you need to speak with someone quickly. Have your original confirmation number and the time you arrived at the gate.

Baggage issues: If your bag did not arrive or was damaged, call within 24 hours of landing. Allegiant will ask for your baggage tag number (on your boarding pass) and a description of the bag. Keep any damaged items and receipts for replacement costs.

Refund requests: Allegiant processes refunds by phone or through its website. If you booked directly with Allegiant, call to request a refund. If you booked through a travel agent or third-party site, contact them first — they handle the refund, not Allegiant directly.

Disability accommodations: Call at least 48 hours before your flight to request wheelchair information, oxygen, service animals, or other accommodations. Allegiant needs time to arrange equipment and staff.

When the phone line is not your best option

If your issue is not urgent, the website chat or email may be better. Allegiant's website allows you to submit a formal complaint or feedback form, which goes to a supervisor and generates a reference number. This is useful if you want documentation of your complaint for a credit card dispute or insurance claim.

For questions about Allegiant's policies — baggage fees, cancellation rules, or what is included in your fare type — the website FAQ section often answers these faster than calling. You can also find this information in the confirmation email Allegiant sent you when you booked.

Frequently Asked Questions

Does Allegiant charge a fee to call customer service?

No, there is no fee to call Allegiant's customer service line. Standard phone rates explore based on your plan, and international calls may cost more depending on your carrier.

Can I change my flight by phone?

Yes. Call 702-505-8888 with your confirmation number. Allegiant will charge a change fee (usually $25 to $75 depending on how close to departure you are) plus any difference in fare. Some fares do not allow changes at all, so the representative will tell you upfront if your ticket is changeable.

What time of day has the shortest wait?

Early morning (6 a.m. to 9 a.m. Pacific time) and mid-week (Tuesday through Thursday) typically have shorter waits. Avoid calling in the evening, on weekends, or within 24 hours of a major holiday.

What if I booked through a travel website, not directly with Allegiant?

Contact the website where you booked first — they handle changes and refunds for third-party bookings. Allegiant can look up your reservation by name and confirmation number, but they will direct you back to the booking site for most changes.

Can I request a refund by phone?

Yes, if you booked directly with Allegiant. Call with your confirmation number and explain why you want a refund. Refunds are processed back to your original payment method within 7 to 10 business days. If you booked through a third party, contact them instead.
