I'm traditionally a poor student, and have only ever travelled in Economy cabins during my various jaunts across the pond to the US and back again. However shortly I'll finally finish the five years it's taken to get myself an MENG in Aeronautical Engineering, and I'll be emigrating across to the US. In celebration of this, I've accrued a small fortune (at least to me) and am planning on blowing it on travelling in "style".

Since I know nothing of travelling outside of economy, I thought I'd pick the brains of you chaps as you all have a wealth of experience. The only real non-variables is that I'll be flying ABZ - DEN, (Although if necessary I could split the flight so as to be LHR - DEN instead).

I'll probably have around £4,000-ish, with the capability of going a bit higher. What product would you recommend? Particular Airline? Thanks for your thoughts or opinions.
