How far ahead of time should a traveler submit a refund request? Applications for discounts must be made approximately 30 days after the ticket's expiration date on Korean Air. For international trips, the passenger must present the discount request at least 91 days prior to the departure date. Korean Air Refund Policy definitely alludes to the fact that, provided they have purchased refundable tickets, travelers may search for discounts. The plane won't be obligated to compensate the passengers if they have non-refundable tickets. If you have a non-refundable Korean Air ticket, you will be expected to pay a few dollars for domestic fares and $200 to $500 for international tickets.
