Numpo-Nigit,
How about this - you bring the slots nicely forward and let us worry about being ready for flight. I understand how hard you might be trying, but if you can, then you should.
If we made a bad decision and haven't got our pax in time for a new slot, then someone else will have to have it.
Now there's is a USEFUL "intervention" if there ever was one. Isn't there?
