You are correct No Skypriority.
However do this all the time.Firstly check how many US flights are going out at roughly the same time. If not a lot then 35 mins before take off is fine, otherwise 45 mins is plenty. The lounge is only 5 minutes walk from US immigration and customs.
BEATS Clearing this in the US on arrival especially if you have a tight connection
