Did anyone else interpret BN's 'letter of introduction' description as 'rock up to your local ticketing office and get a ticket when you need it'?
Not so; First fill in an old paper ticket application, get a letter from Benefits for specific flights & dates, then go to the HONG KONG office of that airline to get the tickets.
NB; specific flights and dates, not an open ticket, and you need to repeat the above process every friggin time. Benefits told me 'its at the Airlines discretion' so good luck with convincing the local office girl its legit
