I am not 100% sure whether this is indeed an SIS or rather RAM issue. Probably it's a point which bothers other airlines too tough.
At LH we were wondering what to do, when an AWARD coupon was billed by mistake under SC01, e.g. the FBTD wasn't identified as FF-like.
I assume OAL fully rejects on SC04, claiming this being an AWARD coupon.
What now? Should the coupon be taken out of the SC04 invoce and billed under SC90, akin to the Sampling Form C process? Or should it be rejected on SC05 which doesn't make sense from my p.o.v. ....
The same question arises for coupons being accidently billed under SC90, which actually should have been billed under SC01 though.
Please advice. Thanks.
