I kinda felt like hitting the lottery yesterday (Wednesday) flying MH economy as a OneWorld Emerald.
Managed to get into the business class transfer at C gates stating emerald and got on an empty business bus. (I asked the counter as I think it is only for business class and MH platinum). After a few minutes a huge group came to board the bus and staff asked me if was flying MH and if I would prefer the BMW which was there just dropping off a passenger. If course I was happy to help
