I love the look and the ease of selecting a destination idea.

When it shows out-of-country options like "Grand Cayman" it routes your flights from your location to "FL" (closest airport to Cayman) and then seems to drop the ball there. The results for skyscanner shows cayman, but I don't see the flight anywhere. It's not a clear UI.

Small thing, you must type the airport identifier in caps ("LAX" vs "lax") if you want it to find it.
