Funny you mentioned this as my MAD-DME leg had not been re-issued by the ticketing department last month. Interestingly, boarding pass for MAD-DME was issued but with no ticket number printed on it (no-one had picked up on it but me!) RTW Desk were apologetic but no explanation were offered either. Luckily I was connecting from JNB so I had time to ring AA RTW Desk to get the ticket reissued before my flight.
