Agree the lounge (MH use the No.77 lounge for their biz passengers) is nothing special. However as noted by carrotjuice, don’t leave it too tight - I arrived 90 minutes before that flight last Thursday and barely made it through in time - both theForeigner immigration and the subsequent security scanning queues were incredibly slow moving. It’s odd - they don’t make it very easy getting in OR out of the country!
