These upgrades are eligible for all fares except S, T, K, L and G in all BusinessFirst markets.


I assume CO will need to recode their fares to suit this schema. in the CO world, S isn't necessarily the lowest, and G is actually quite high (on some routes).

I wish there was a hybrid - i.e 4 SWU no restrictions or 6 with restrictions.
Trying to use this, or give it away will be a problem.
