James, unfortunally i, personally, dont think that much will be diverted to MSE. The ramp can only handle 2 A320s at a time, as im sure you are aware. And the terminal building can only accomadate 300-400 pax at anyone time. I can however see the Oasis HK flights divert to MSE, as they said last year they will use MSE as there divert airport.

Mate the ramp can handle four A320 or two 747 , When BA went on strike they wanted to use MSE 😎 I see if I can find out if airline is going apart from Oasis.
