If you are buying a large cabin jet card, and distance is an issue, make sure to check with your provider which aircraft might be offered. Fuel stops add time and additional expense from longer routing and taxi time charges, typically 12 minutes per segment, or for simplicity, at a $15,000 hourly rate, an extra $3,000. In fact, there are quite a few large-cabin jets that would require a fuel stop flying westbound to the U.S. from Europe (against the winds), depending on where you are coming from and going to.
