Also, you get the perk with the associated letter? I thought it was a random draw?
"G.O.A.T", and that should answer airports_manager question too:
Learn to Play, page 14:
When you level up, you draw two random S.P.E.C.I.A.L. tokens
and choose one to keep. If you do not already have that token,
add it to your player board. If you already have that token, you
get a perk instead! You return the token to the supply and search
the perk deck for the perks that match that token, and then
choose one perk to keep.
1. draw two
2. choose one
3. a) if you don't have it, add it to your board
3. b) if you have it, choose one perk that matches that token
You choose first, and then act accordingly if you already have it or not.
