Selling Aircraft?

I'm new to this, and started with leasing 10 year old planes usually for 3 years.  When I had excess cash flow, I started buying out the leases early.  But now I've decided that I wanted to gradually replace those old planes I own with new planes.  How to I put my unused old planes up for sale once I take delivery of the new replacement planes?

On the aircraft details page there is a sell button. There is a buyer under that button. 

Thank you!  I found the sell button you mentioned.  So one I idle a plane and click sell, does it just get posted on the "Used Aircraft for sale" page so that I have to wait for it to be bought, or does the system immediately take it off my hands and give me the cash?

supposedly it gets put on the market but I have no proof it actually does

You get the cash immediately. In theory, the aircraft should appear on the 'for sale' list but it seems to take a few days.

Recently, in a world where I have two airlines, one was able to buy an aircraft that the other had sold. What was a bit odd is that although the first airline sold 12+ aircraft I only saw one, even though I had been watching the list closely.
