A couple of weeks ago I was on a business trip and we decided to take Virgin America. We ended up on first class. I don't think I've every had a flight seem so short. We boarded and immediately began playing with the gadgets. First class is much better than coach. We turned on the massagers, laid back the oversized chairs and put on our favorite private movies. We could listen to music, watch TV, etc.
We had a blast. In contrast, we came home on coach. At 6'4 we were both cramped into the seats. We didn't have the same luxuries.
Concierge.com has a whole different take on comfort in the air. Beds in private suites, etc. are the ticket. Check out the article: http://www.concierge.com/ideas/luxuryspa/tour/detail?id=1543&page=1
