The UK's air traffic control service, NATS, is preparing for the influx of traffic this summer for the 2012 Olympic Games by planning significant changes to the airspace surrounding London. In addition to airspace restrictions and procedure changes, arrival and departure slots will be required at the 40 airports closest to London. "Book early to avoid disappointment. People who want to get closest to the center of London must book early," warned Stephen Patterson, the coordinator for all activities related to the 2012 Olympics at UK NATS, in this week's NBAA Flight Plan podcast.
