EK 380
Been lucky enough to do 2 sectors on the Emirates 380, 1st time paid for an upgrade froy C to F to try it, and it's very nice, not spectacular, but very nice. 2nd time got a comp. upgrade at the gate, so that was nice, but the sectors were Dubai - Bangkok, after night flights from the UK on 777s with the "sleeperette" seats, so all I wanted to do on both occaisions was put my bed flat down and get some much needed sleep.
Do I prefer it to the 777, definately, but always feel safer in a Boeing, but thats just me !
