I flew back from HKG last night on the BA28. I had dinner in the Pier at about 9.30pm and then a glass of champagne in the Wing before boarding. I got onboard ready to sleep and managed to sleep until the start of breakfast service. I needed to get back to Cambridge promptly after landing so having breakfast onboard worked better today than going to the arrivals lounge.
Flight times back from HKG are very good for sleeping and the Cathay First Class lounges are excellent. Enjoy!
