For the rest of us who aren't CEOs, Arab royalty or Taylor Swift, here is how you get to fly on these babies.

I've had the opportunity to ride on a number of Bombardiers and a G550. Having the meal, snacks, and drinks of your choice waiting for you on the plane is just too cool, as is being able to bring your dog and whatever dangerous things you might be using for hunting later. They pump oxygen the whole time too, which doesn't happen on commercial carriers unless you berate or beg the Capt. I don't remember the last model I was on, but remember being really impressed with the ride, and loved how there are secret little chambers built into everything. You see a rectangular cut out on this shelf next to you, push it, and it rolls away revealing chips and candy. Push another down by your feet and boom, it's loaded with cold beer. My only complaint was the size of the head. Turns you into a hunchback. No standing to take a piss or joining the mile high club in that. Not having to deal with a terminal full of people, security, then off to claim bags is pretty damn awesome though, that needs to be said!
My folks were doing a Scotland trip years ago. Going across the pond limits what plane you can reserve due to range, obviously. They decided to go all out and use the Gulfstream. They left with tail winds, and combined with the altitude and speed of the Gulfstream, made it from Maine to Scotland in some ridiculous time (forget what it was exactly). I remember my dad telling me that the pilot mentioned upon landing that the flight had been the fastest Atlantic crossing of his career, just missing a company record by minutes. Only way to do it faster would be in a Concorde. Btw, Lockheed and a company called Aerion both want to bring civilian supersonic travel back in the not too distant future!

Gulfstreams rule, it's true.
