some of your ideas/dreams (like Jules Verne) have been realitiy some times ago (15 years?). With Swissair first-class (paying a fortune, and their was no business yet) you were allowed to ask for your favorite steward/stewardess to be on that flight (and they did their best to accomodate you) and entering the plane - your seat and your luggage compartement had your name "printed" on - and my steward knew my favorite drinks, wines (from our company) and meals - GOOD OLD TIMES (but without the fun of mileage-programs).
At that time I asked for my military-adjudant (sorry that's french, I don't know the english word for it: something like "military-male-secretary"?) who happened to be steward with Swissair - and it was fun (on the flight and at the destinations) for both of us.
