U.S. Department of Transportation (DOT) regulations set the minimum compensation airlines like Spirit must provide for involuntary denied boarding on overbooked flights. This applies only when the airline bumps a passenger against their will due to oversales. For domestic flights, compensation equals 100% of the passenger's one-way fare if alternate transportation arrives 1-2 hours after the planned time; it doubles to 200% (maximum $400) if the airline fails to rebook within 2 hours. International flights use 1-4 hour and 4-hour thresholds for the same structure. The one-way fare is calculated to the next stopover or destination.
These DOT rules establish airlines' minimum obligations and do not cover voluntary bumps, no-shows, or general delays. Contact Spirit customer service first for compensation, gathering your boarding pass, itinerary, delay proof, and fare receipt as evidence. If denied, file a complaint with the DOT at dot.gov/airconsumer.
DOT Rules Control Involuntary Denied Boarding Compensation
DOT regulations, outlined in the 2008 Federal Register, limit compensation to cases of involuntary denied boarding from oversold flights. Airlines must solicit volunteers first and explain their boarding priority process before bumping anyone involuntarily.
| Flight Type | Delay Threshold for 100% Fare | Delay Threshold for 200% Fare (Domestic Max $400) |
|---|---|---|
| Domestic | 1-2 hours | Over 2 hours |
| International | 1-4 hours | Over 4 hours |
The compensation uses the passenger's one-way fare to their next stopover or destination, paid under DOT minimums. Airlines like Spirit must comply as the federal floor.
What Does Not Trigger DOT Compensation
DOT rules do not require minimum compensation for voluntary denied boarding, where passengers accept incentives like vouchers or rebooking. The airline sets those terms without federal mandates. DOT overbooking rules differ from separate regulations on flight delays or cancellations. Credit card chargebacks or state consumer laws do not govern denied boarding compensation; pursue those only after exhausting airline and DOT processes.
Next Steps and Escalation for Spirit Airlines Bumps
Request compensation from Spirit customer service or their claims process immediately after the incident. Provide your flight details, boarding documents, and proof of delay or rebooking time.
Evidence Checklist:
- Boarding pass or confirmation
- Itinerary showing original and actual arrival times
- Fare receipt for one-way calculation
- Communication records with Spirit
If Spirit denies the claim or underpay, submit a complaint to the DOT online at dot.gov/airconsumer. The DOT has enforced these rules against airlines for non-compliance.
