Congrats
Joel,
Are you the same guy who started the thread "Comair vs. Netjets" about 2 weeks ago? If so, congrats about the Citation X - I think you will love the flying. I agree that Netjets presents a better opportunity than commercial flying. Sure, you can always make more money in the majors (excluding United, USair...), but the fractional flying will be more interesting - and you will get to fly brand new, high-tech corporate jets to a much-greater variety of destinations...
Starting off in the Citation X will be a great introduction - flying .92 mach and into Aspen every now and then can't be too bad a gig. And with all of the new aircraft orders, you'll likely be a Captain in no time.
Congrats and have fun flying FAST in the X!!!!!! Good job.
