Corporate jobs can be broken down into a few areanas.
1. 91 corporate. 2. Fractional lease (91k) 3. 135 charter.

I currently fly part 91 corporate for a construction company. Works great for me. I have a pretty fixed schedual and rarely have over nights which allows me to be home with my family. I fly about 300-400 hrs per year and rarely work weekends. The drawlback is when companies start losing money or the plane goes is for maintenence they always want to sell the plane. I've had 3 scares in the last 2 years.

Fractionals like netjets and options will typically put you on 7 on 7 off, but I have heard of cases of 10-15 on and 3 hard days off. There is also a lot of opportunity for overtime. So if you start at 30k-35k you can make up to 45k with overtime, but you won't be home. Upgrades range from 3-5 years. But with net jets attrition is low (nobody's leaving) so the upgrade could be a slow crawl. I have also heard of companies overselling plane shares so crews end up jumping around looking for an uncrewed plane. If your looking at fracs I look into netjets- they just cleared up a TA.

Then there's 135 charters. This is kinda like the wild wild west of aviation. Some companies are legit but a lot are fly by night and run as satellite opps on some other companies chater cert. You won't have a schedual and will be on call every day of the year. Some cases you could be called in less then an hours notice. You also have to be careful with the front end hiring process. some companies want you to pay for a type on the front end and then go out of business before you show up to work. Duty times are also a factor. The FEDs can access logs 30 days back and will fry you if you are over crew/duty times.

Corporate may have you doing a lot of job hopping but then again so could the airlines. You can also plan on cheap owners, sitting around in FBOs all day and drinking bad coffie. Just happen to work for me.

Hope that helps.
