How Do You Change Your Flight for Korean Air Online?
Ticket holders manage existing reservations and make flight changes by clicking the My Trips tab on the Korean Air homepage. Site visitors log in using their SkyPass numbers or User IDs or look up reservations using reservation numbers, flight numbers or names on the reservations.
Terms and conditions vary based on the type of flight that is booked, so date changes might not be allowed for all bookings. In addition, changing the date of a flight is contingent on current availability.
As of April 2015, ticket change fees apply for economy-class bookings. Change fees are waived for some types of first-class reservations.
