I just went down to the MH ticket office at KL Sentral to get an MH operated flight changed on a CX issued DONE3.

Not only did they refuse to even look at making any changes, but they told me to talk to SQ.

Now, I've had a number of xONEx tickets in the past issued by a mix of QF, AA and CX and every time I've needed a change done, QF, AA, BA, CX, AY and JL have done it without complaints - regardless of who was operating the flight in question or who issued the ticket.

I think MH needs more training.
