I am not 100% sure but I think you print it out and then bring it to the lift ticket line with you and they reload it. However, I do not know for sure. This posting is on Google, so you are not asking an employee by posting here. I would say it is best to call, or contact them on Facebook. Their page is "blue mountain resort"
Haven't tried reloading online yet this year, but if you already have an account set up they likely have your card number stored
I've usually had to log in to my own account first, which links the transaction to the card. Check if you are logged in.
