CX only have "International" flights...
Their long haul business class product ("New Business Class") originally reclined to 13 degrees. Wide body aircraft fly and an incline of around 3 deg so the net "angle" was 10 deg. As posted here, they're in the middle of a retro-fit ro reduce it further.
I did more 500,000 miles (96% with CX) while living in HKG a few years ago. Brilliant.
In SIN after that, becoming PPS with SQ within 7 months... The
Singapore Girls just make the service that touch more personable as I believe their English is a bit better on average. This just makes them a bit more at ease and able to interact with their customers a little more freely. But, the product is the same as CX - on small differences which make no real differentiation.
As to the seats, the best position to sleep on CX/SQ/QF seats which do not go "flat" is an "S" position. Leave the back up a little and the footrest down a little. You feel like you're in an arm chair. This way, you get great sleep and most importantly, you don't get a
wedgie!
Three biggest differences between CX and QF are:
1) CX have "Audio-Video On-Demand". So, you can watch what you want, when you want - pause, rewind etc etc. They have whole CD collections on their server to play in their entirity or make your own customised play-lists. QF are only offering this on their new A330s - and we know how many of them they have. It makes a huge difference, especially on day flights.
2) The CX meal service - they bring out all the parts of all the meals on the menu (the "makings") and allow you to choose what you want (and how much). So, if you prefer rice to potatoes, you can mix and match!
3) The CX staff don't have "attitude", aside from a desire to give you good service

. On a SIN-SYD QF flight, can't believe I was told I couldn't be served some water as they'd be "doing the meal service soon". They use your name and don't call you "mate" (whether Johnny and Kim like it or not!!) :wink:
CX are currently offering the "Regional Business Class" on their A330s to BNE, CNS, PER and DBX. Still get the great services as described in 2 & 3 above. Note that all their 777 fleet (intra-Asia) has their Regional Business Class product - freshened cabin and bigger TVs, "traditional" meal service.
