My wife and I fly from the US east coast to Europe once or twice a year. We used to fly Coach but after a particularly bad experience decided to try First Class (on a two class flight). Now we can't go back to Coach. The experience is that much better. Instead of being an ordeal to be endured the flight forms part of the vacation. A word of advice, though. Don't try it unless you're willing and able to fly in the front from now on. Once you've experienced First or Biz going back to Coach will border on unendurable.
