To back up these recent comments, last week I went to Hong Kong on Cathay Pacific in business. At check in at BKK I asked for the blue card, was told wasn't required and guards at fast track checked our boarding cards and noted we were in business and let us through. On the way back, no cards given out on the plane. We headed to the fast track immigration section and I said to the guard there that we don't have blue cards, he said not required, checked boarding passes for business and let us through.
