I think it costs 100Euros for a pin but that's it.
Point 5 is correct in what he says if related to a normal Slot Revision Message (SRM). But if you send an REA with a MINLINEUP of 5' then all that TIS + Taxi stuff goes out of the window. If you tell us you can get the aircraft on the runway in 5' then thats what we use to calculate the slot.
Gonzo: If you are sending REA messages without a minlineup then your Slot revision will be based on your taxi time. If thats 10' then of course you will receive a slot only 10' in the future. If you ARE including a minlineup then we will use that figure.
