A shiny project containing all out-bound flights from California in 2015 + useful metadata

This dashboard contains information about all flights that departed from California (e.g. LAX, SFO, SAN, OAK, e.t.c) to destinations in the United States, Puerto Rico, and the American Virgin Islands) in 2015: 674,000+ flights in total, with an average of 1850 flown from California daily and 19% delay of the total flight.
