I flew the new A330 with Swiss from New York in First. The seat is far more comfortable and is fully flat compared to that on the A 340. I actually managed to sleep from just after t/o to 30 minutes before landing at Zurich.
The “Maitre de cabine” mentioned they would start to fit the new seating in the A340 from March but I don’t know how correct that is. A Swiss captain I know quite well said he had heard rumours but nothing substantive just yet.
I’m flying JNB – ZRH on Sunday, so I will try and see if anyone knows some more.
