I think at the very least it's going to take some work to make use of the pass. I hope you like solving puzzles. There might be ways around the overnight layovers because Frontier's IT does not allow two stop trips unless there is no plane change. So you need to self-construct two bookings for a one way and assume all the risks of doing that. Look for the first one stop trip to end by 4pm or 5pm so you can have a second onward booking end on the same day. For some of us, this IT limitation makes the pass viable because hardly anyone will do the work or pay for a 3rd party monthly subscription that makes this puzzle faster to solve.
