So the website is erroring for me on what ever FF# is entered as passenger number one during booking. Claims the number does not exists and stops the booking process, when the number clearly does exist.

I've been trying to book for five days (since 10/26) and continuously receive the same error. Five days and they still have not fixed it.

I think the problem is that no one can be logged in. Everyone's Frontier number must be added manually. In your example, your wife cannot be logged in (and neither can you).
