Checking of details for 311 airports

I have a list of airports with general properties such as geo coordinates, name of the airport, city etc. However these properties may be wrong. Based on the IATA code of the airport you need to lookup the exact location of the airport and check other general properties such as the official name, city, country etc. The list is long, but only 311 airports need to be checked. You can use google maps also for looking up the exact location and geocoordinates (if you click right and select what's here you get the geocoordinates of any place worldwide).
