I was totally unaware until IFS advised me of it on PVG-SIN flt 2 weeks back - that is why I inquired to SQ Feedback. She also told me at time - after consulting her handbook - that indeed SQ had only 2 new 77W with New Gen F so apparently 3rd one into op since then.Mr Ng did call me a week back just to clarify a couple of points and did say it would take another week to respond in full - it is what I expect from SQ.
I think the *new* does a lot of the SIN-LHR route from memory. Would be nice to see on the MEL-SIN run however...
SQ really show how it's done with customer service. Many other travel companies could take note.
