Well having spoken with many friends of mine in the US the word on the street is that YES smaller jet aircraft such as the Challanger/Citation/Learjet/Gulfstream
are all being considered for use for their executives rather than using the airlines.
The jet goes when you want it and if you are late it waits for you....
The pilots are known to you and therefore there is less chance of it being hijacked if any at all....
So as for some of your replies such as "bollox" just shows what pratts you really are.....
Executive jets are the way forward...
