Maybe it was when your business class seatmate started coughing and sneezing – and didn’t stop for three hours – due to “allergies.” Maybe the breaking point was when one of the twin toddlers sitting right behind first class spent the whole flight screeching. However it occurred, you’ve decided that you’re ready to try private jet travel.
