I have an unusual question.
Can you change the frequent flyer number on an award ticket?
For example, I am a Skyteam elite plus member with KE, but I booked an award ticket using my Delta skymiles(on Delta website) for a CI flight. Skyteam elite plus can check-in one extra piece of luggage, and have lounge access. So I want to change my Delta award ticket(flying on CI) to show KE flyer number and Skyteam status.
Is this doable? How and when to do this? At airport check-in counter?
Thank you.
