Easy booking, didn't get jerked around with "false fares" (which has happened repeatedly on Priceline.) After booking I was notified that one of my flights was changed because I hadn't paid for an upgraded "premium" seat. That was bothersome, but supposedly has been handled during a follow-up call with Cheap Flights. I've been told I now have my original flight again and that a seat assignment was being made for me (next to my wife.) Downgraded one star because I wasn't given my new seat assignment for that one flight when I was notified of confirmation of my booking, and therefore I'm not yet certain that it happened.
