As good as it gets
Not sure how people typically rate apps, but for me, I compare it to what is available amongst competitors. This is by far the best app for nailing down the cheapest airfare. It allows you to search by date, allows you to easily scrolled to see cheaper dates, identifies nearby airports as alternatives, and, The kicker is, it finds cheaper fares that arent available anywhere else using airline pricing tricks that the airline doesnt want you to know.
