The cost of flying privately continues to soar, according to the latest data from Private Jet Card Comparisons. In the third quarter, the price of fixed-rate guaranteed availability jet card memberships increased by 4 percent, to an average hourly rate of $11,200 across all business aircraft types. That continues the trend of rising jet card costs that began at the first of the year with a 5 percent quarter-over-quarter increase early this year and another 6 percent increase from the first to the second quarter.

Economists who consider cryptocurrency without merit have likely never tried to book a last-minute charter flight after banking hours or paid the high credit card fees levied on a trip costing tens or hundreds of thousands of dollars. Because although the charter industry is built partly on the promise of being ready when you are, that pledge is conditional: airplanes don't move until operators get paid, and cryptocurrency advocates say it can sometimes be the best solution for making quick, low-fee bookings. Moreover, notwithstanding this year's collapse in cryptocurrency values, customer demand for digital currency payment options continues.
