CX Opup for AA Emerald
Very pleased to be given a complimentary upgrade from Y to J upon check-in here at Changi (Singapore) on a Cathay Pacific segment to HKG. My next segment, long haul to SFO, is ticketed in business but this first flight was booked in coach.
My next four hours will be far more pleasant, thanks to a OW airline being willing to op-up elites of partner airlines.
