First transAtlantic in U's 330s was fantastic. My last trip with with my wife, Rome to PHL -- we were the only two passengers in first. Going over we had a air marshall across the cabin. One F/A in each direction.
From 1993 to 2001 I was over and back on U transAtlantic every three weeks -- all in Envoy or first. Great people! got to know the rythem of the flight, where the sun was and the time (westbounds), how much longer the flight, and more. Eastbound, my trick in not getting jetlag was to have no caffeine or alcohol and very little protein the day of the flight. I'd have pasta at either PIT or PHL. On the plane I would only have salad. Take an aspirin and sleepy time tea, and got a good six hours sleep. Would awake when I felt the first move to initial descent. Get up, put shoes back on, go wash up, and get ready for landing. Actually nice memories. Westbound, with a window seat, I got my best concepting and creative writing done. I always called USAirway's transAtlantics my best working productivity tool.
