Just a quick update here... flew CX711 HKG-SIN this afternoon, and it doesn't look like there were any negative effects due to the upgrade apart from the website being down. Check-in at the airport was smooth (at the J counters, at least), and, to most pax, they probably wouldn't have noticed anything if they didn't go to the website.

On a side note, the coffee at the refurbished Wing is not bad at all.
