Hi there. I am planning heading to Berlin in mid September, probably 13th - 22nd (dates are somewhat flexible). I would probably fly out of Sea-Tac, but I could fly out of Vancouver if there was a good reason for it. I'm pretty new flying and miles, but I have managed to accrue 60K UR points. Looking at flights on ITA, it looks like roundtrip airfare in economy is about $1300. So here is my question (2 parts):

1) If I fly Air Berlin, I can transfer my UR points and use 50K of them to upgrade to business class (nominal value $6700, so +$5400). Does this seem like a good value?

2) Is it worth flying business class for a flight of this length? I am 5'-9" 130lbs, so I fit OK in economy. My flight experience is limited to economy class in 737's for trips around 4 hours, which I generally find pretty comfortable. I'm not sure how this extrapolates to a transatlantic flight.

Any help or recommendations are greatly appreciated!
