Not clear on question. You can use your June 2019 points for any trip that ends May 31, 2020 or before. You cannot use them for any trip that begins on or after June 1, 2020 unless you first bank them. If banked, they can only be used for a trip that begins and ends between June 1, 2020 and May 31, 2021. Once you bank the points, the 11 month/ 7 month rule applies, e.g., if you banked them today, you could make a reservation right now using them for a trip beginning Sep 25. 2020 at your home resort.
