I had always wanted to ride on the upper deck like you, and last week I flew to Asia on the lower deck with a return on the upper deck. I may not be in the majority here, but I prefer the lower deck. For me, it feels less claustrophobic and I can stand up at my window seat without bumping my head.

Just as the other thread says, you'll have to fly to Asia, but you could also fly a KLM 747 to Amsterdam. I recommend KLM MD-11 in WBC in the small forward cabin (my favorite). Check it out on www.seatguru.com.

Good luck!
