Ferry Flight Passenger
There are a couple of Ferry Pilots that will take the odd pilot passenger but not many as most have done this in the past and refuse to do it again unless they are a good friend. Many ferry pilots won't even take the owner along!
Are you a UK or US citizen?
If you are a UK citizen you will need a USA Visa to get into the USA on a private flight.
Depends on how available you are as many ferry flights are very last minute and you need to be able to go at the drop of a hat.
