DOT Complaint Timeline: How Long Until Resolution
DOT complaint timeline: from filing to resolution, what happens in each phase. Day 0 filing, day 14 airline acknowledgment, day 30 first substantive response, day 60 deadline, and what follows if unresolved.
The Standard Timeline
The DOT complaint timeline follows a predictable cadence for most cases: filing, airline acknowledgment, first response, DOT review, resolution. Total duration: 30 to 90 days for simple cases, 90 to 180 days for cases involving DOT enforcement review.
Day 0: Filing
Complaint submitted at aviationconsumer.dot.gov. DOT generates a case number. You receive an automated confirmation email. DOT forwards the complaint to the airline within 3 business days. For filing step-by-step, see dot complaint process step by step.
Day 7 to 14: Airline Acknowledgment
The airline's consumer affairs team logs the complaint. Many carriers send a templated acknowledgment within this window (Delta, Southwest, Alaska). Low-cost carriers may not acknowledge separately.
If you receive an airline settlement offer in this window, evaluate carefully. First offers are sometimes below the DOT-rule minimum. Verify against the rule before accepting.
Day 14 to 45: Airline Substantive Response
The airline investigates and issues a response. Three outcomes:
- 1
Full settlement (refund, compensation, voucher plus cash).
- 2
Partial settlement (offer less than DOT-rule amount).
- 3
Denial with justification (often a claim of extraordinary circumstances or passenger fault).
Day 45 to 60: DOT Review
If the airline's response was a denial or insufficient, DOT reviewers examine the response against the rule. If the response is clearly non-compliant, DOT may contact the airline with corrective guidance.

Beyond Day 60: What Happens If Unresolved
- ›
Congressional inquiry: your senator or representative writes DOT; often escalates to airline C-level quickly.
- ›
State AG referral: some state attorneys general (California, New York, Massachusetts) actively pursue airline consumer cases.
- ›
Small claims court: for amounts under state thresholds (typically $7,500 to $15,000).
- ›
DOT enforcement action: pattern of complaints against a carrier can trigger formal enforcement proceedings.
