My goal is to fly to Europe with my gf and treat her to a nice trip. I have miles on Alaska, Delta, British Air and US Air. My home airport is PDX, but SEA is a short 3 hour drive north so either departure point is fine. Plan is to fly into one city (not decided yet) and then take the train to multiple destinations. We would fly home from the other end of Europe 10 or 12 days later so it would be an open jaw for sure.

We want to fly business class, but we also want to be able to sit together and talk during the flights. Most of the products I have looked at are great for single travelers as people get their own little space. However, we would like to enjoy the time together as well as have a nice experience with the little egg shapped pods, ect. The only requirement is we want at least one of us to have window seats.

Considering who I have miles with, which product (airline and aircraft) will be the best product for my needs? Estimate date of departure is about 9 to 12 months away.

What are your thoughts?
