The fractional world is all about change. Everything changes multiple times a day. You are paired up with a crew and a plane and are on call for all of your duty periods for that tour. It could be late night shows, it could be early morning shows, and more often than not it will be a mixture of both on the same tour.
To me the flying is more interesting than the 121 world. You will go to places you have not ever heard of along with all of the airline hot spots. You will be tasked with making more decisions, both operational and customer service, with your crew than in the 121 world. There are many things that you have seen in airline flying and there are a lot you will learn as you go.
It is a different skill set, something anybody can learn if they are willing to, than flying for the airlines. I think that when the legacy 121 airlines start hiring the fractionals will see the departure of some of their pilots and hiring will resume. If you are looking at the larger fractionals don't expect a quick upgrade. I have been at NetJets just under 5 years, 40 from the bottom and it will be at least another 10 years for me to see the left seat of a small cabin airplane.
Best of luck to you.
