One of OpenFlights‘ most popular features is our dynamic airport and airline route mapping, and today, we’re proud to release the underlying data in an easy-to-use form, up to date for October 2009.  Behold 56749 routes between 3310 airports on 669 airlines spanning the globe:

The data can be downloaded from our Data page and is free to use under the Open Database License.  In addition to IATA and ICAO codes for airlines/airports, which can be difficult to use due to controlled duplicates and code recycling, we also include the unique OpenFlights identifiers that can be used for easy cross-referencing to our airline and airport databases.  So, for example, a route map entry like this:

BA,1355,SIN,3316,LHR,507,,0,744 777

Can be cross-referenced to the name, codes and country of airline 1355:

1355,"British Airways",N,"BA","BAW","SPEEDBIRD","United Kingdom","Y"

As well as the name, codes, location and even timezone of airports 507 and 3316:

507,"Heathrow", "London", "United Kingdom", "LHR", "EGLL", 51.4775,-0.461389,83,0,"E"
3316,"Changi Intl", "Singapore", "Singapore", "SIN", "WSSS", 1.350189,103.994433,22,8,"U"

As always, we’d like to thank the folks at Airline Route Mapper for doing the hard work of collecting and maintaining the route data, all we’re doing is repackaging and providing it online.

Routing for the winners,
