I can top that K1ngston – just flew back with the family on CX from Bali. Was paged while I was in the lounge, offered an upgrade to business class for myself and the Memsahib (hell, yes!), got the greeting as a CX Diamond (BA Gold equivalent), and even – get this – the Memsahib and I were both offered the opportunity to reserve our main course choices in advance to ensure we didn’t miss out.
Always addressed by name (without any of that silly looking them up on a piece of paper) throughout the flight. That is the part that CX do exceptionally well. I don’t know how they do it – I am terrible at remembering names, but it seems that within a very short time of getting on the flight, all the FAs know the names and faces of all the premium passengers. Consistently impressive, and shows real personalisation of service.
