WSSS will not stay locked forever.

The five-star list is recalculated every day. It reopens to everyone the moment this airport drops below the bar — and any airport that climbs into the list is opened by the same Pro, with nothing to re-buy.

What stays free.

The other 21 airports stay free, in full, for everyone — including guests. Pro adds the top-rated airports; it does not take anything away. See the whole board.
