This is why I like to research recommendations. Looks like a lot of mixed views here on Brokers in general so let's look at the obvious question. What is the best way to go if you are looking for a convenience and cost effective way to travel to anywhere in the US and Europe(western) on a moments notice?

-Good broker? Then which one?
-Purchase an aircraft and perhaps share the privilege/expense with a colleague or somehow figure a way to make money with the jet when you are not using it.
-Hire somebody to identify a few relevant charters that can handle your needs and then deal with extended notice requirements that these charters will bring.

I think the 2nd and third options are the way to go. The 3rd being the most attainable.
