14 CFR Part 260: What the Automatic Refund Regulation Actually Says

14 CFR Part 260 automatic refund is the US Department of Transportation regulation, effective October 28, 2024, that requires airlines to issue prompt cash refunds to original payment methods when a flight is cancelled or significantly delayed and the passenger declines to fly. The full rule is published at ecfr.gov under Title 14, Chapter II, Part 260 and at transportation.gov/airconsumer/refunds. Before this rule, US airlines often steered passengers toward flight credits instead of cash refunds. Part 260 closed that loophole.

The rule is unconditional. There is no carrier exception for weather, ATC, mechanical, or any other cause. When you decline to fly the rebooked option, the cash refund right triggers and the carrier must process within 7 business days for credit card or 20 calendar days for cash and check.

• ›

  Cancellation: any cancellation by the carrier, regardless of cause, regardless of how far in advance.

• ›

  Significant change in flight schedule: defined as 3+ hours domestic or 6+ hours international that the passenger does not accept.

• ›

  Significant change in flight itinerary: passenger downgrade from a more-direct routing to a substantially different routing not accepted by the passenger.

• ›

  Class downgrade: involuntary downgrade from a higher class of service. Refund of the fare difference.

• ›

  Lost or substantially delayed baggage: 12 hours domestic, 15-30 hours international (under the related 14 CFR Part 251 rule). Refund of bag fees, separate from Montreal Convention liability.

Part 260 defines significant delay as 3 hours or more for domestic flights and 6 hours or more for international flights, measured at arrival, when the passenger declines to fly the rebooked option. The arrival measurement matches the EU261 Sturgeon doctrine on door-open arrival time.

• ›

  Domestic 3-hour threshold: the rebooked itinerary arrives 3+ hours after the original scheduled arrival.

• ›

  International 6-hour threshold: the rebooked itinerary arrives 6+ hours after original scheduled arrival.

• ›

  Arrival time definition: door open at the destination, not wheels down.

• ›

  Codeshare: the operating carrier rules apply. A US-numbered ticket on a foreign-operated international flight uses the international 6-hour threshold for the actual operating carrier.

The refund right triggers when the passenger declines the rebooking. 'Declined' is not a strict legal term in the rule, but practical interpretation requires explicit notice to the carrier that you do not want the rebooked itinerary.

• ›

  Explicit decline at the gate or counter: 'I decline this rebooking under 14 CFR Part 260 and request a cash refund to my original payment method.'

• ›

  Decline via the carrier's portal: most major carriers have a refund request page. Submitting starts the clock.

• ›

  Decline by email or phone with the carrier's reservations team: save the case number and timestamp.

• ›

  Implicit decline: if you simply do not show up and do not communicate, some carriers treat this as a no-show, not a decline. Always be explicit.

• ›

  Boarding the rebooked flight then disputing: undermines the decline-to-fly trigger. Pick one path: take the rebooking or refund, not both.

• ›

  Credit card refunds: 7 business days from the carrier processing the refund request. The clock starts when you submit the request, not when the disruption occurred.

• ›

  Cash, check, debit card refunds: 20 calendar days from the carrier processing the request.

• ›

  No carrier exception: weather, ATC, technical, none waive the deadline.

• ›

  Original payment method only: the refund must go to the same card or account used for the original purchase. Carriers cannot route to a different account or issue store credit.

• ›

  Full ticket value plus fees: the refund is the full unused fare plus all related fees (baggage, seat selection, change fees if applicable).

The 7-business-day clock is the most important enforcement tool. When the carrier exceeds this window without a refund, the DOT complaint at transportation.gov/airconsumer is your immediate next step.

Part 260 covers involuntary class downgrades. If you booked business class and the carrier rebooks you in economy, the fare difference is refundable.

1. 1

   Confirm the original fare paid for the higher class.

2. 2

   Confirm the fare for the same itinerary in the lower class.

3. 3

   Refund equals the difference, processed in 7 business days for credit card.

4. 4

   Carriers sometimes try to substitute miles or status credits. Decline; insist on the cash refund.

Substantially delayed baggage triggers a separate refund of the checked bag fee under 14 CFR Part 251. This is in addition to (not instead of) Montreal Convention liability for documented loss.

• ›

  12-hour domestic delay: bag fee refundable.

• ›

  15-30 hour international delay: bag fee refundable.

• ›

  Lost bag: bag fee plus Montreal Convention up to 1,288 SDR (USD 1,710).

• ›

  Multiple bags: each bag fee refundable separately.

DOT enforces Part 260 through civil penalties against carriers for systemic violations. Recent enforcement examples include Southwest's 2024 settlement following the 2022 holiday meltdown, Air Canada's $4.5M penalty for COVID-era refund violations, and multiple foreign carrier penalties under the new rule. Individual passengers cannot recover penalty amounts directly, but DOT pressure typically resolves individual refund disputes in 60-120 days.

Part 260 is the most powerful US passenger right because it is unconditional. Decline rebookings explicitly when you want the refund.
