Worst response from the airline side (go first) as well as mmt. I asked for cancellation of partial pnr for a round trip and they cancelled the round trip and said that the PNR S8DD7Z for a round trip gets cancelled for both ways. Imagine I'm on a trip n all I'm doing is communicating with the travel agent and airlines for hours for an error created at their end. Same issue for my other PNR A3FRQY happened because of the airlines. They create errors and we have to bear the losses.
