In comparing any jet card pricing, make sure you are comparing apples to apples. Different providers include or exclude different charges in the main, headline prices they quote. Other features also differ from provider to provider, including the age and type of the aircraft, call out times, discounts for round trips and termination and refundability. Another area of difference is the number of peak days in the card program. These can vary from under 20 to over 50, and some companies charge extra for peak day travel and for most they require extra notice to book an aircraft.
