I only have FlyTampa St Marteen and Tampa downloads - nothing else. My head is spining with all the options - freeware, Aerosoft, ORBX, REX, Megascenery, Newport, Taburet etc.I am looking for major US airport and cities.It seems ORBX only doe Australia, and small US airports. FlyTampa has 2 or 3 US Cities for FSX I can get. But who makes the best NY City Scenery? I'd like Chicago and NY with JFK, LGA, EWR ORD and Midway detailed for starters.Any advice?My computer is pretty high end so I could handle the frame rate hit - but I am not too good installing this stuff - so I need a simple install. How are the free addons?

You'd probably best be served by FS Dreamteam. They have airports for the following US majors...KJFK, KORD, KDFW, KLAS, KLAX, as well as some others.
