UA can not sell F seats on ORD-NRT. It might end up having a cabin full of upgrades. But many of those people might not have bought a ticket on UA at all if it wasn't for the upgrade. I think many FT'ers would buy ORD-NRT on NH or JAL when the company is paying, but then end up buying on UA or AA because they can upgrade to F.
Excellent point, hindukid!
F-class in this cases helps retain full-fare business class customers!
This has been confirmed more than once by my TA who serves several corporate customers flying paid business! And this strategy is not only employed by U.S. carriers.
