I am doing an award which the last leg is PRG-ORG. I'm going though AMS now but want the stamp from PRG.

I set up alerts on EF for DL (class Z) and OK (class Z). These were chosen from EF. Today the DL came through and I was notified. I called the PE desk and was told the class is actually "O".

According to EF "O" if Business class and "Z" is PMU points or upgrade.

Does anybody know the actual class code?
