But it works out the other way many times as I have a family friend who bought a Hawker 400 card and found himself flying on an Ultra most of the time as netjets told him that all light jets are fully interchangeable. He felt it was quite a bit of a bait and switch game as he bought one plane and found himself on a much inferior plane.
Out of curiosity, what was the deciding factor to purchase the card in the 400xp rather than the Ultra? 9 out of 10 times I think our Marquis owners buy the 400xp simply due to greater availability. As already said, the Ultra overall is a much better airplane. The only thing a 400xp has over an Ultra is a small amount of speed and all 400's are much newer than the Ultra's, that is it. The company ironically considers the 400xp an upgrade to the Ultra due to the aformentioned reasons, it is a complete joke! I wish they would correct that, it would be much easier for us pilots to do our job to the fullest.
