I've flow to Zurich from Oklahoma once. I was in coach on the way there..and it was miserablely cramped ( being that I'm 6'3 ). On the return trip I lucked out. The flight was over-booked and they put me in Business class. I had a recliner, anything I wanted in the way of snacks and drinks. and a portable DVD player with a huge book of movies to watch.

I wouldn't fly trans-atlantic in anything other than first or business class ever again.
