Thanks for your comments Non-NonRev. I used the search feature and I didn't come up with the answers I needed.

The Concorde trip is extremely hard to justify to myself and family as I am on the road far to much already. As a former commerical pilot I really want to have a trip on this plane before it retires, but first I have to "sell my family" on it.

I hate to say this, but unless somebody can give me some ammunition to justify the trip, my Marriott points will pay for weekend family trips - so sad
