I selected this flight managed by cheapflights using KAYAK. I immediately got a 20 dollar discount. But then, i wasn't getting e-ticket confirmation. (Another flight I booked that same day with United using Kayak immedialy sent an e-ticket confirmation). I called Cheap Flight; and was told that it wasnt sending the-ticket because I didn't pay enough; and Cheap flights charged me another $23. THEN I rec'd the e-ticket confirmation. This process is clearly a scam by Cheap Flights. Cheap Flight also sent 2 different confirmation codes. Cheap flights didn't makeit clearwhich one I needed to use on the Frontier Airlines w\app. So I ahd to call cheap flight again to have this explained to me.
