Allegiant Air Headquarters and Corporate Office
Allegiant Air is headquartered in Las Vegas, Nevada. Allegiant Travel Company lists its headquarters at 1201 North Town Center Drive, Las Vegas, NV 89144. This address is useful for readers searching for Allegiant Air corporate office, Allegiant Air headquarters, Allegiant corporate address, Allegiant HQ, or Allegiant Travel Company corporate office.
Allegiant is a leisure-focused airline known for low base fares, nonstop routes, vacation destinations, smaller-city service, optional add-ons, and package travel options. Because airline issues are often time-sensitive, travelers should use Allegiant’s official trip-management and customer-care routes before mailing written correspondence.
Allegiant and Sun Country Corporate Update
Allegiant Travel Company completed its acquisition of Sun Country Airlines in 2026. During the integration period, Allegiant says travelers should continue using the airline they booked with for reservations, customer service, check-in, loyalty programs, and airport support.
That means Allegiant customers should continue using Allegiant.com, the Allegiant app, Allegiant Customer Care, and Allegiant airport support for Allegiant-booked travel. Sun Country customers should continue using Sun Country’s own support routes for Sun Country-booked travel unless Allegiant announces a change.
Choose the Correct Allegiant Support Route
Use Allegiant Customer Care or Manage Travel for reservations, flight changes, cancellations, Trip Flex questions, seat assignments, baggage purchases, check-in problems, boarding passes, payment issues, Allways Rewards questions, and travel credits.
Use the Allegiant contact page, email/feedback option, text support, or Customer Relations mailing address for post-travel complaints, compliments, unresolved service issues, and written documentation. Use airport staff for same-day airport issues, boarding, baggage reports, flight interruptions, wheelchair assistance, or urgent accessibility help.

Before contacting Allegiant or submitting a complaint, gather:

- Receipts, emails, screenshots, payment records, or text alerts
- Baggage tag number or claim report number if the issue involves luggage

Include the confirmation number, flight numbers, travel dates, passenger names, receipts, baggage report numbers, screenshots, and the resolution you are requesting.
DOT Airline Complaint Option

DOT complaints may be relevant for unresolved airline service issues, refunds, baggage problems, disability-related air travel concerns, discrimination complaints, tarmac delay concerns, and other airline consumer-protection matters.
For disability-related concerns, Allegiant’s Customer Service Plan says a Complaint Resolution Official, or CRO, is available through the Reservations Department and at airports during regular hours of operation. Travelers should document dates, names, flight information, and what assistance was requested.
