Yes, things do change at FCO, and *A companies have recently moved their checkin operations to T1, previously reserved for AZ and Skyteam. Since I haven't flown into FCO recently I don't really know whether they've also moved the arrival into the basement of T1 or whether they keep T3 when bussed. I must confess that, as a Greek, I'm used to this unique consistent feature of living in a Mediterranean country: everything is inconsistent!
