you know, I am somewhat curious

When I am on my flights and I hear other airlines with their callsigns and flight numbers, like CX289, or NZ1 or something like that. I am always curious: where are they going to or where are they coming from.
During my flights I have no chance to check it, only when I write them down, and when I get back home then I can check the internet for it.
Now my question: Does anybody know if there is some "masterschedule" for every major airline? Which I can download and then enter airline and flight number and the program shows me the routing?
I guess something like this doesnt exist...
Or do I have to download every schedule of every airline itself? I hope not

Thanks for the help guys
