My experience has been the polar opposite. These guys sold me a membership offering empty leg access to "a fleet of over 300 jets" but it quickly became clear that this was a lie - presumably to inflate membership ranks before their SPAC last year. Soon after I joined they removed the TMC Hawkers from the empty program, and later stopped posting any empty legs on the DPJ fleet. As far as I can tell they have never included the Mountain Aviation Citation Xs. Basically, you get occasional access to empty legs on the King Airs, with the odd Citation from the Gamma fleet sprinkled in.
To make things worse, despite specifically telling me that everyone had the same access to the program, they later admitted that Connect members get push alerts and booking access 15 minutes after the more expensive memberships. That means I'll get a push alert for an attractive flight only to open the app and find that it was booked by someone else before they even made it available to me.
Connect is a complete waste of money.
