Unfortunately, this did not work. This is just such a strange problem. Opa, thank you for all the help you have given me, if you or anyone else, have any idea what this problem is, feel free to post it here. As for me, I'll see what I'll do and I'll re-post whether I installed something wrong or I'll post a fix to someone who might be facing this also. Thanks for your time and help.

I have made about all the suggestions I can think of - and as you say, this is really strange - as I, and many others have not experienced what you have described.You might want to post your issue (with as much detail as possible) on the World of AI forums.You do have to "register" (which is free and easy) in order to see all of the forums and make posts - but the guys there are extremely helpful. Perhaps they can suggest something I have not thought of.http://www.world-of-ai.com/Forum/index.phpGood Luck!!

These are my installed airlines:I watched a video on youtube and at Schipol, the airport was flooded with traffic, Just one single terminal was completely packed with Northwest Airlines (which I have installed). When I actually start flying, I do have a decent number of planes taking off and landing but the actual planes at the gates is just too low compared to what I had on fs9 and what I have seen on youtube which makes my aiports seem unrealisitc. Please, someone help me with this strange problem.This is my schipol.

Okay, I have dense airports now! What I did is that I completely re-installed fsx with my antivirus, firewall, etc. completely off. Then in fsx, I flew around a little with the default planes. As I went back to the sim, the number of planes increased. After playing with the default planes, I re-installed woai packages and my airports are dense like in fs9. The only one that wasn't dense was schipol (I had already installed KLM for example, and there were literally no planes at the airport), but I re-installed KLM and NWA and my Schipol became completely filled with KLM. To conclude, I think that both my FSX never installed correctly, and that some of my packages simply don't install correctly sometimes and I need to re-install them.

The fastest way of having dense airports filled with WOAI aircraft is to set the default traffic slider into custom. On that area, if you have the packages reinstalled already, set the airline traffic slider into 100 and that should fill your airport with hundreds of aircraft. I'm not sure if Opa had answered the question with the same reply. It's pretty much of a challenge when you go on a 747-400 on an airport filled with OTHER 747s or any other wide-body aircraft, because the plane's dimension are so large, that you'll need to be cautious of tails that are in the brink of hitting your cockpit.
