Better one in the hand than two in the tree...
My friend ~
I drive a Global 5000 for a nice guy. Long hauls, from telaviv to anywhere from all over europe all the way to russia, hong kong and mauritious.
But alas, times have changed and I would be thankful to simply reposition the bloody plane from one airport to the next.
So long as you're still holding onto a job that pays, keep it. Now is not the time to be searching for something. There are so many others that don't have a job that could any chance of one more than you and I.
Come the time and things change, no question that you would be better off with some heavier experience plus type if that is your sort of thing. It is a pretty nice deal.
