Do we know what KE plans on doing with F cabins for planes that are operating them but don't have F fares for sale (77W)? Run them empty or upgrade elite members (with Prestige-level service)? I'm assuming that it's more likely an equipment swap will happen to a plane with no F in them, but just curious how they will plan on dealing with that? I'm looking at SFO-ICN and they will have 77Ws operating later this year (November), but no First Class is available and I'd bet they'd just revert to 787-9 if First Class and overall ticket sales don't return closer to normal by then.

As Digicola said, I think KE will just run out the clock on this. If F cabins are reinstated to more destinations beyond LAX or JFK, they can just open them up for award inventory post-devaluation after April, while the rest of us who are trying to book at pre-devaluation rates will be out of luck.
