Delta AirElite is too expensive. You deposit $100K, and they charge you $4,750 per our on Light Jets, whether it's a one way or a round trip. On peak periods (i.e., during any holiday week) they charge you $7,125 per hour on Light Jets, whether it's a one way or a round trip. I'm talking all inclusive hourly prices before tax.
There are jet companies out there that charge far less on the same aircraft and with the same safety standards. For example, if you fly on a Light jet with JetCard Plus, they charge you $3,950 / hr for one ways and $2,950 / hr for round trips. Same during peak periods. And they pioneered a card membership program. Again, I'm talking about all inclusive hourly prices before tax.
