Probably totally unrelated... but reminds me of an experience with RJ also at CAI. Checked in, business class, CAI-AMM-FCO and was met with "no, it says your sector is flown". Obviously it wasn't... (it was part of a OneWorld Explorer). Took half an hour of stern talk with the contract staff before it magically fixed itself.

Given what a total hole CAI is, and how corrupt it is, I wonder if there is some kind of a bribery scam going?
