34 | A demo application designed to help compare application deployment methods between

36 | application uses TripIt profile data to find upcoming flights, helping you determine
37 | if there are flight or weather issues, and providing potential alternative routes to
38 | your same destination. Follow the link below to authorize this application to your
39 | TripIt profile.
