How to File a Complaint with Allegiant Air: Form, Deadlines, and DOT

To file a complaint with Allegiant Air, go to allegiantair.com/contactus, choose “Email Us,” and submit the online form with your confirmation number, flight details, and a clear description of what went wrong.¹ Federal rules then require Allegiant to acknowledge your complaint within 30 days and send a substantive response within 60 days.² The written form is what creates the record you need if the airline goes quiet and you have to escalate.

Use the Online Form, Not the Phone

The “Email Us” form on allegiantair.com/contactus is the right starting point for any complaint involving money or a documented problem. It timestamps your submission and gives you something to cite later. Allegiant also offers live chat through its virtual assistant and a text line at +1 (866) 432-6165, and the customer service phone number is (702) 505-8888, but a call does not produce the written trail that triggers the federal response-time rules.¹ Save the phone for quick rebooking questions. For refunds, reimbursements, and damage claims, put it in writing.

What to Gather Before You Open the Form

Have your booking confirmation email open. The form will ask for your confirmation number, the flight date, and the departure and arrival airports. Pull together everything else you’ll need before you start typing, because the form is easier to fill in one pass than to revisit:

Your flight number and the scheduled departure time.
The departure and arrival airport codes (for example, SFB to PIE).
The right issue category from the drop-down (baggage damage, flight delay, accessibility concern, and so on). Picking the right one routes your complaint to the team that handles it.
Receipts for any out-of-pocket costs you want reimbursed: hotel, meals, ground transportation, replacement items.
Names or badge numbers of any employees central to your complaint, and the gate or counter where the interaction happened.

Writing a Description the Airline Can Act On

The description field is where complaints succeed or fail. Open with your flight number and the scheduled departure, then walk through what happened in order. A sentence like “Flight 2147 was scheduled to depart SFB at 3:15 PM on March 12; at 2:45 PM the gate agent announced a mechanical delay, and no update was given until 5:30 PM, when the flight was cancelled” tells the airline exactly which internal records to pull. Stick to what you observed. Skip the editorializing.

End with a specific ask. “I am requesting reimbursement of $187.43 for the hotel and $34.00 for ground transportation, receipts attached” works far better than “I want to be compensated.” Concrete numbers signal that you expect a concrete answer.

Baggage Complaints Have Shorter Deadlines

If your complaint involves luggage, the online form is not your first step. For domestic Allegiant flights, damaged bags must be reported to an airline representative at the airport within 12 hours of arrival. Missing contents must be reported within 24 hours.³ Go to the baggage service counter before you leave the airport, file the claim, and keep a copy. Photograph the damage while you’re still there.

Allegiant can deny claims that are incomplete, lack receipts, or describe damage inconsistent with the bag’s documented condition.³ After filing at the airport, you can still submit through the online complaint form to keep a parallel written record.

After You Submit

Once you send the form, an automated confirmation should arrive at your reservation email within a few minutes. It contains a case or tracking number. Save it. Every follow-up call, reply, or escalation should reference that number. If no confirmation shows up within an hour, check your spam folder and resubmit if needed.

Allegiant handles most follow-up by email. Accessibility issues may generate a phone call instead. Don’t submit duplicates while you wait; one well-documented complaint moves faster than three vague ones.

Automatic Refunds for Cancellations and Significant Changes

If Allegiant cancels your flight or makes a significant schedule change, you are owed an automatic refund to your original form of payment. DOT rules require the refund within 7 business days for credit card purchases and within 20 calendar days for cash, debit, or other payment methods.⁴ The airline cannot force you to accept a voucher instead.

Baggage fee refunds follow the same 7/20-day timeline if the airline fails to deliver your checked bag by its own baggage delivery deadline.⁴ If the refund is late, note the dates in your complaint; it strengthens any later escalation.

The 30-Day and 60-Day Response Rules

Under 14 CFR § 259.7, Allegiant must acknowledge your written complaint within 30 days of receiving it and send a substantive response within 60 days. “Substantive” is the key word. A form letter that says “we got your complaint” satisfies the 30-day acknowledgment but does not satisfy the 60-day requirement. The 60-day response has to address the specific issues you raised and explain Allegiant’s position or the resolution it is offering.² Put both dates on your calendar when you file. They are your leverage.

If Allegiant Doesn’t Deliver, File with the DOT

If the airline misses either deadline, sends a non-answer, or refuses a refund you believe you are owed, file with the DOT’s Office of Aviation Consumer Protection at airconsumer.dot.gov.⁵ The DOT encourages you to try the airline first but does not require you to exhaust every internal option before filing.⁶

Have your booking details, flight dates and numbers, city pairs, and a copy of your original complaint to Allegiant ready before you start the DOT form.⁷ The DOT forwards your complaint to Allegiant and directs the airline to respond to you with a copy sent to the agency.⁵ Your Allegiant case number and a timeline of what the airline did or didn’t send will make the DOT filing substantially stronger.
