Is there a word limit on DOT complaint narratives?

The DOT online form has a character limit for the narrative field, typically around 2,000 characters. Keep your narrative concise and factual. If you have extensive documentation, summarize in the narrative and attach the full documents.

Do I need to attach documents or just describe them?

Attaching documents strengthens your complaint. At minimum, attach your booking confirmation and the cancellation or delay notification. If you have written correspondence with the airline, include that too. Complaints with documentation are resolved faster.

Can I file by phone instead of online?

You can call DOT's Aviation Consumer Protection hotline at 202-366-2220, but online filing is faster, creates a written record, and allows document attachments. Phone complaints are logged but carry less weight than detailed written complaints.

Can I amend a DOT complaint after submitting?

You cannot edit a submitted complaint, but you can submit a follow-up communication referencing your original complaint number to provide additional information or update DOT on new developments.

What if I do not know the exact delay length?

Use the flight tracking records from your booking confirmation or a flight status service like FlightAware. For cancellations, the exact delay length is irrelevant. For delays, you need to establish that it was 3 or more hours domestic or 6 or more hours international.

Can I file for a flight that was delayed but not cancelled?

Yes. The DOT final refund rule covers both cancellations and significant delays. A significant delay is defined as 3 or more hours for domestic flights and 6 or more hours for international flights. The same template and submission process applies.

How long does DOT take to contact the airline?

DOT typically forwards complaints to airlines within 5 to 10 business days of submission. The airline then has 30 days to respond. You can expect the first substantive action on your complaint within 6 to 8 weeks of filing.

Can I use this template for a flight booked with miles?

DOT refund rules apply to cash ticket purchases. Award ticket refunds are governed by the airline's frequent flyer program terms and by DOT rules on taxes and fees paid in cash. The template can be adapted, but the regulatory basis may be different for miles-based bookings.

Where to Submit and How

Go to transportation.gov/airconsumer. Select 'Airline' as the service provider type, then select 'Refund' as the issue category. Fill in the airline name and your flight details in the structured fields. Paste the complaint narrative above into the description or narrative text field. Upload your documents as attachments (PDF or JPG are both accepted). Submit and immediately save or screenshot the confirmation page, which contains your complaint reference number.

Save your reference number. The DOT complaint reference number is essential for every subsequent step: your demand letter Version 3, your chargeback dispute, and any small claims filing. Without it, you cannot reference the complaint in other proceedings.

What Happens After You Submit

DOT sends your complaint to the airline's customer relations department with a copy of your narrative and attachments. The airline has 30 days to respond to DOT. DOT reviews the response against your complaint. If the airline's response is inadequate or their conduct clearly violated the DOT rule, DOT issues a finding in your favor. If DOT determines your claim is valid and the airline is unresponsive, DOT may open a formal enforcement inquiry that can result in fines against the airline.

Total expected timeline from submission to finding: 60 to 90 days. For the full claim timeline comparison across all paths, see the flight compensation claim timeline guide.

Combining With a Chargeback

You can file a DOT complaint and a credit card chargeback at the same time. A federal regulator and your card issuer are both now in the loop, and the airline has to respond to both. The DOT complaint reference number also strengthens your chargeback by showing the card network you tried to resolve it directly before escalating.

For the complete chargeback dispute letter template, see the chargeback letter guide. For the full DOT complaint walkthrough, see how DOT complaints actually work.
