How to File a Complaint with Frontier Airlines (Step-by-Step Guide)

When something goes wrong with a Frontier Airlines flight, getting help can feel unusually difficult. Delays, cancellations, baggage issues, and refund problems are common complaints — and many passengers struggle to get clear answers or responses.

This guide explains how to file a complaint with Frontier Airlines, what to expect at each stage, and what to do if customer support stops responding. It’s written for travelers who need practical steps, not generic advice.

When You Should File a Complaint with Frontier Airlines

You should file a complaint if you experienced:

A delayed or canceled flight

A refund that was not issued or processed correctly

Lost, delayed, or damaged baggage

Unexpected or unclear fees

A lack of response from customer service

Complaints should be submitted as soon as possible. Waiting too long can reduce your options, especially for baggage-related issues.

Information You Need Before Filing a Complaint

Before contacting Frontier, gather the following information:

Confirmation code

Flight number and travel date

Passenger name(s)

Description of the issue

Receipts for any out-of-pocket expenses

Photos of damaged baggage or property

Complaints without documentation often stall or receive automated responses.

Frontier Airlines Official Complaint Process

Frontier primarily handles complaints through its online contact system.

Search:
“Frontier Airlines customer support” or “Frontier Airlines complaint form.”

Select the option that best matches your issue:

Flight delay or cancellation

Refund request

Baggage issue

Customer service concern

Frontier does not prioritize phone support for complaints, so written submissions are usually more effective.

How to Write a Complaint That Gets Read

Structure matters. Use this format:

Identify the flight and date

Explain what happened

Describe the impact (financial or logistical)

Request a specific resolution

Example:

“Flight F91234 on April 3, 2025 from Denver to Orlando was canceled due to crew availability. I was rebooked for the following day and incurred $142 in hotel and meal expenses. I am requesting reimbursement or travel credit.”

Avoid emotional language. Clear documentation increases the chance of review.

Frontier Airlines Refund Timelines

Credit card refunds typically take 7–14 business days

Other payment methods may take longer

If your refund exceeds this window, escalation is appropriate.

Lost or Damaged Baggage With Frontier Airlines
At the Airport

Report the issue immediately at the Frontier baggage desk

Request a file or reference number

After Leaving the Airport

Submit a baggage claim through Frontier’s website

Upload photos and receipts

Baggage claims must be reported promptly. Delays can limit compensation.

What to Do If Frontier Does Not Respond

If you receive no response after 7–10 business days, move to escalation.

File a Complaint With the U.S. Department of Transportation (DOT)

Search:
“File a DOT airline complaint”

The DOT forwards your complaint directly to Frontier Airlines and requires a formal response.

Include:

Original complaint text

Dates of contact

Case or confirmation numbers

Supporting documentation

This step often produces results when airline support stalls.

When Problems Continue Despite Escalation

Some travelers experience ongoing issues such as:

Repeated non-responses

Conflicting information from support agents

Lost baggage that remains unresolved

Refunds delayed indefinitely

When this happens, documentation becomes critical.

This is where PublicMinute can help.

PublicMinute helps travelers organize complaints, track communication attempts, and structure documentation when airlines stop responding. It does not replace airlines or regulators, but it helps ensure your issue doesn’t disappear into support queues.

PublicMinute is especially useful when:

You’ve contacted Frontier multiple times with no response

You need help tracking communication timelines

You’re preparing documentation for escalation

Clear records often determine whether a case moves forward or stalls.

What Frontier Airlines Is Legally Required to Do

Frontier Airlines must:

Issue refunds for canceled flights not rebooked

Respond to complaints submitted through the DOT

Follow its published Contract of Carriage

Frontier is not required to:

Provide compensation for inconvenience

Offer hotels or meals unless specified

Refund non-refundable tickets without qualifying conditions

Understanding these boundaries prevents wasted effort and frustration.

Best Practices for Communicating With Frontier

Use written communication whenever possible

Save screenshots, emails, and receipts

Keep a timeline of events

Avoid relying on verbal promises

Documentation increases accountability.

Summary: How to Get Results With Frontier Airlines

Gather all documentation

Submit a structured complaint through Frontier

Request a clear outcome

Escalate to the DOT if no response

Organize records if communication breaks down

Most unresolved complaints fail due to missing documentation, not lack of merit.
