Hi,
I fly to our europe office quite a bit.
Always use United or American.
Portland to DC, Dc to vienna via Austrian Airlines.
I love Austrian Airlines, good services, movies and screens on every seat.
American is ok too, but transfers suck.
Portland to Dallas, Dallas to Zurich, Zurich to Vienna.
I always just watch 2 or so movies, sleep a little, eat a little, and by that time your almost there.
Not so bad if you don't smoke
