Now this is interesting. How well did UDUs work on pmUA when it was an OAL ticket or codeshare? Maybe you can explain?

Can't comment on OAL, but PMUA didn't allow on codeshares to participate in UDU. Some reported luck in being added to the list at the airport, but by rule, this wasn't supposed to happen.
