Well, I am starting to think that when I next make a booking for an owe I am going to have the reservation agent put a comments in the booking for every sector to show how it fits in with the rules. My itinerary ex CAI ending in DXB was rejected by the Dublin rate desk with a message "Must end in CAI". Oh well now the local AA office (SYD) are going to battle it out for me.

My advice is to save yourself the hassle and get the res agent to comment anything that might seem unusual.
