Hi everyone-

I will be flying Korean Air from Seoul to Seattle in about a month...I have a Global Entry Known Traveler Number, but have only ever used it when flying Delta back into the USA. (Delta has a spot in my profile to store my KTN in my preferences)

Since Korean Air doesn't have a profile section to input your Known Traveler Number, can I still using GE when arriving back at Seattle?

Does your KTN even have to be on your ticket to use Global Entry?

Thanks in advance for the help!
