Asiana Club - F from ICN to PUS

Last year, when I flew from PUS to ICN I was on a economy ticket and I asked for an upgrade and the check in person told me that she could put me up front. When I got on the plane I realized they were F class seats. I will be flying from ICN to PUS and would like to book the F seats but they seem not to be available. I think I was on a 733 or 319. Can anybody help?

Asiana does not sell business class on domestic routes. They sell only Y class, as far as I know. What I heard is that when there's C seats, OZ upgrades loyal customers to those seats without any charge. So you can ask when check in again. ICN-PUS is operated by A321 and A320 now. Some of 320 does not have C class seats, then you'll be denied.

Had this come up on several flights to CJU; got an "upgrade" just for being tall; most of the time without even asking.

KE is actually selling domestic J if you want to make sure to sit up front. Korean domestic flights are a mass product anyway, so not much need to book in advance.
