Hi,
Just came off BA012 from SIN travelling in Economy on a 787 (can't think of when we last flown so long at the back of the plane), had a great (standard) cabin crew which subtly greeted both me and my travel partner after boarding was completed. [I was lucky that the flight was not full ~80% in Eco and had the seat between us empty].
She was did everything really subtly that it's non-noticeable to other pax.
- during meal times she seemed to only have requested the pax in front of us to bring their seat upright
- when asking for another bottle of wine (walked to the back of the galley) she provided another one for my travel partner
- later (I guess before she ended her shift) came by us to ask if we needed anything - mentioning even if we want it from Club - (we did not really know what, since champagne in Club was nothing) - she suggested snacks with our drinks and she came back with a basketful of snacks and 2 bottles of water and a bottle of wine
- when deplaning, she wished us a pleasant onward journet back to AMS

in general she was also very kind to the rest of the pax

Hopefully this is a trend going forward for BA - small gestures which costs them nothing. Both of us submitted an online Golden Ticket.

Cheers!
