Want to join the Mile HI club? There’s a new app, the MileHi app, that allows fliers to meet-up before, during or after their flight.

Unlike many social networking sites that rely on GPS, MileHi allows users to track each other via flight number. Users can also chat via private message to see who’s on different flights. Others have launched social networking apps for fliers in the past, but most have not had overwhelming success.

The MileHi app is the most downloaded app during check-in and the most deleted app at baggage claim. The app has been downloaded 3,000 times in its first week.
