As for booking the specific RDB, could I ask what travel agent you have used to book your flights? That would surely be annoying to have to call MH, but if you know of any online TAs, that would be greatly appreciated!
I’m not aware of any OTA that lets you pick and choose specific RBDs. If anything they’re meant for people who don’t care about that sort of thing.
You’ll need to talk to a human behind a computer – at MH, Amex, or a brick and mortar TA – to book exactly what you want.
