Why do I keep getting oversupply warnings?

[Flyer32]

I have a 757 that i am desperately trying to put on routes but keep getting oversupply warnings.  It is getting really frustrating that I cant seem to fly this thing anywhere.  How on Earth do I find out how to either scrap the thing or put it on a route that works?  It is getting to the point that I dont even like this game anymore.

Sorry, but we cannot look into the demo, so you have to give us a few more infos, such as:
1) Where are you based?
2) Where are you trying to fly the thing?
3) Are you opening the routes without looking into route planning first?

And on a general note, regarding oversupply warnings, you have to mind the return leg. Watch that, it sometimes has demand significantly different to the way there.

Can you not just cap the capacity on the route edit page?

Worked for me when I had warnings post the 9/11 slump on MT8
