Does anyone know any websites to get information on airports?
Google? lol
For US airports the FAA is a great place to start and where I find most of my passenger numbers:
http://www.faa.gov/airports_airtraffic/airports/planning_capacity/passenger_allcargo_stats/passenger/
Also, visit the individual airport's website, as often they have information on passenger/cargo movements through their facility.
thanks guys...i'll be sure to take a look
