Next you'll be wanting "somewhere new" and "somewhere fun".

"somewhere new" - sounds good, keep track of cities I've previously booked flights to and exclude these from my results

"somewhere fun" sounds good too. It could keep track of your ratings of places you've been and recommend new places based on that.
