Q about Slots not returned to pool

[rubiohiguey]

A quick question about slots not returned to pool:

After I cancel the route and uncheck the box "return the slot to pool" I keep it. I already tried it. But is there a way (place) to track of the slots I have paid for and I kept (not returned to pool) but that are going unused at the moment?

Thank you.

If you look at the slots page for the airport, you'll see * everywhere you have an unused, paid for slot.

But if you forget which airports you have unused slots at, there is no way to see a list of them, other than to wait for the messages that say you're about to lose them.
