DOT Complaint Process Step by Step
DOT complaint process step by step: how to file on aviationconsumer.dot.gov, what evidence to attach, how long the response takes, and when to escalate to congressional contact or press inquiry.
When to File a DOT Complaint
The DOT complaint is the formal escalation path after the airline has refused or ignored your claim. You do not file a DOT complaint first; you file with the airline first, wait up to 30 days for a response, and then escalate. The DOT complaint process step by step unlocks enforcement attention and often forces airline settlement within 30 to 60 days.
Where to File
File at aviationconsumer.dot.gov. The online form is the fastest path. Paper filings are accepted but slower. See significant delay under DOT what triggers a refund for context on what counts as a complaint-worthy delay.
Every complaint is logged and published in the DOT's monthly Air Travel Consumer Report. Patterns of complaints drive enforcement action against carriers.
Information You Need Before Filing
- 1
Flight details: date, flight number, airline, origin, destination.
- 2
Booking reference and ticket number.
- 3
Timeline: scheduled departure/arrival, actual departure/arrival, notification times.
- 4
Documentation: airline emails, boarding pass, rebooking details.
- 5
Prior complaint to airline: date filed, airline response (or lack of one).
- 6
Requested resolution: refund amount, compensation amount, specific remedy.
What to Include in the Narrative
Keep the narrative factual and timeline-based. Skip emotional appeals. The DOT reviewer is a professional complaint handler, not a customer service agent. Lead with: "On [date], flight [number] was [cancelled/delayed/denied boarding] under circumstances that trigger [DOT rule]."
Reference the specific DOT rule that applies: 14 CFR Part 259 (refund rule), 14 CFR Part 250 (denied boarding rule), 14 CFR Part 259.4 (tarmac delay). See dot complaint proof what to attach for the evidence list.
The 60-Day Response Window
Once filed, DOT forwards the complaint to the airline with a 60-day response deadline. The airline must substantively respond to DOT, not just to you. In about 60 percent of cases, the airline settles directly within the 60-day window to avoid escalation.
If the airline's response to DOT is inadequate, the case stays in DOT's queue for further review. This is where enforcement actions sometimes originate. See dot complaint timeline how long until resolution for detailed timing expectations.
Escalation If the Complaint Stalls
- 1
Contact your US senator or representative. Congressional inquiries on DOT cases frequently unlock settlements.
- 2
Small claims court. For refund or IDB amounts under state small-claims thresholds (typically $7,500 to $15,000), small claims is a low-cost option.
- 3
State AG consumer protection complaint. Some state attorneys general actively pursue airline consumer cases.
- 4
Press outreach. For egregious cases with documentation, aviation trade press and consumer reporters occasionally amplify.
File Your Claim
The DOT complaint is one tool in the claim process. Before filing DOT, file with the airline first. Check your flight and we handle both steps. For additional context, see the denied boarding compensation guide and the US DOT passenger rights pillar.
