I have had two sectors on A380 F recently (1A and 2K) and the service difference between the was like night and day....1A being far better and 2K service not existing. Having said that, not exactly solid stats and my next flight I'm in 2K as the A side is full.
Zol, I agree with UKDoctor -- your service deficit does sounds like a crew issue rather than a configuration or equipment issue.
My understanding is that the A380 and B777 experiences differ quite a bit. Most people seem to be huge A380 fans. I'll be traveling on 777-200LR for 2 - 141/2 hr segments, and on 777-300ER for 2 +/- 8 hr segments. Thankfully all 4 segments do show suites.
I changed my seats to 2K for the trip. Any other EK tips from those of you who are regulars?
