How the US DOT 24-hour rule works

The 24-hour policy is grounded in a U.S. Department of Transportation (DOT) regulation that applies to airlines — including foreign carriers like Korean Air — selling tickets for travel to, from, or within the United States. The rule requires airlines to do one of the following:

• Allow a free 24-hour hold on a fare without payment, or
• Allow a full refund within 24 hours of purchase if you cancel.

Korean Air follows the free 24-hour cancellation/refund approach: you pay at booking, and if you cancel within 24 hours (with a booking made 7+ days before departure), you get a full refund. Both of these conditions must be true:

Condition	Requirement
Cancellation timing	Within 24 hours of booking
Advance purchase	Booked 7+ days (168 hours) before departure

 

If both boxes are checked, your refund is 100% and penalty-free, regardless of fare class.

Who qualifies for Korean Air’s 24-hour cancellation?

You generally qualify if:

• You booked directly with Korean Air (koreanair.com, the app, a ticket office, or the reservation center).
• Your flight was booked at least 7 days before departure.
• You cancel within 24 hours of booking.
• The ticket is for travel to or from the US.

You may NOT qualify if:

• You booked through a third party (OTA, consolidator, or travel agent) — their rules apply.
• You booked fewer than 7 days before departure.
• More than 24 hours have passed since booking.

Booked through a third party such as Expedia or a travel agent? You must cancel through that company, and their 24-hour terms (and possible fees) may differ from Korean Air’s.

Does the 24-hour rule apply to non-refundable tickets?

Yes — this is the most valuable part of the policy. Even a non-refundable Saver or promotional fare can be cancelled for a full refund if you cancel within 24 hours of booking and booked at least 7 days before departure. After the window closes, the ticket reverts to its standard rules (base fare often forfeited; unused taxes/fees usually refundable; remaining value sometimes issued as a travel credit). Use the 24-hour window to fix a name typo, correct wrong dates, compare a better fare, or cancel if plans change.

How to cancel a Korean Air flight within 24 hours

Online (fastest, timestamped)

Open koreanair.com → My Trips / Manage Booking (or the app), enter your booking reference and last name, select the reservation, choose Cancel, confirm the full refund, and save your cancellation confirmation number. An online cancellation is timestamped and valid for the 24-hour window.

By phone

Call +1 (888) 217-2892 (booking help). Have your booking reference ready, state you’re canceling within the 24-hour window, and request the refund to your original payment method.

Through a travel agent / OTA

If you booked through a third party, cancel through that company — they process the refund, not Korean Air.

The 24-hour clock starts at the time of booking (not midnight). Cancel with time to spare to avoid any dispute.

How long does the 24-hour cancellation refund take?

Payment method	Typical refund time
Credit card	About 7 business days (may take 1–2 billing cycles to post)
Cash / check / debit	About 20 days
SKYPASS award ticket	Miles redeposited; paid taxes/fees refunded

 

The timeframe starts when Korean Air processes a valid cancellation request. Third-party refunds may take longer.

24-hour cancellation vs. 24-hour hold

Some airlines offer a 24-hour hold (reserve now, pay later). Korean Air’s primary US protection is free 24-hour cancellation (pay now, full refund if you cancel within 24 hours). Either way you get a risk-free 24-hour window — but with Korean Air you typically pay upfront and are refunded if you cancel in time.

Common mistakes that cost travelers their refund

• Booking through a third party and expecting Korean Air to refund you — you must cancel through the third party.
• Booking within 7 days of departure, which voids the 24-hour free-cancellation benefit.
• Missing the 24-hour deadline, even by a short time.
• Assuming “24-hour” means “anytime” — standard fees apply after the window.
• Not saving your cancellation confirmation number.

What to have ready before you cancel

• Booking reference (PNR) and passenger last name
• Flight details and travel dates
• Original payment method
• SKYPASS number (for award tickets)
• Whether you booked directly with Korean Air or via a third party

Korean Air–Asiana merger: does it affect the 24-hour rule in 2026?

Korean Air and Asiana are integrating, with full integration targeted for December 17, 2026, after which Asiana operations move under the Korean Air brand. The good news: the 24-hour cancellation protection is based on US DOT rules, so it continues to apply to qualifying tickets for US travel regardless of the merger. Korean Air-issued tickets follow Korean Air’s process; Asiana-issued tickets during the transition may follow Asiana’s process until systems fully integrate, but DOT protections still cover US travel. Both carriers operate within the SkyTeam alliance, hubbed at Incheon (ICN).

If Korean Air doesn’t honor your 24-hour refund

If you qualify but a refund is refused or delayed beyond the DOT timeframes (7 business days for credit card, 20 days for cash), keep your cancellation confirmation and follow up by phone with your refund reference number. If it’s still not resolved, you can file a complaint with the U.S. Department of Transportation, which enforces the 24-hour rule for airlines selling US travel.
