YUP and KUP fares are technically coach though. They simply are "instant upgrades" to the next class of service while not being true F/A fares. As a result, in the event of IRROPS, one can be rebooked in another
coach fare class or wait till the next flight with F is available (with P fares ranking below true F/A)
OP - Post the detail fare rules if you have them.
