If I had the money, I'd be satisfied with flying in paid F instead of utilizing charter services.... It is only worth it if your time is worth $4,000+ per hour [Some say Bill Gates makes $500 per minute].

On international trips it is $6,000 per hour plus fees [EWR charges $400 just to land], so NYC-LHR will easily be at least $40,000 OW and that does not factor in membership fees. If you want someone to serve you food/drinks on the plane you have to cover all the labor costs. Trust me there are tons of "a la carte" expenses involved

Go and become a professional golfer then seek sponsorship from NetJets or MarquisJets then it is all good!
