My wife and I have an upcoming trip to Japan from IAD
. We are flying in prestige (business class) and are more than excited for the trip. Does anyone know KE
's policy for upgrading to a higher class. We would love to try out the newer Kosmo suite on the IAD
sector. Is this something that could be done at the airport on the day of travel? Do they offer an affordable option to upgrade if the seats are available? Any experience here from any of you folks? Thanks a lot!
