Does anyone know when free friend days are for this month with a season pass?

There is a promotion "bring a friend fot 9.99" is valid untill June 15. And another one for all this month to bring a friend for half price

There isn't a free day.. it costs $9.99. .. june 11,12,13,14,15.

There is a free friend if you have a season pass, its from june 3rd to june 15th only on weekdays

I think six flags also sends emails with additional promotions including additional free friend days, so search your inbox too.
