You can link up to two bank accounts to your Hilton Honors Debit Card, however only one account can be active at any time. The active account is the one we will debit when you spend on your Hilton Honors Debit Card.
When you add a second bank account, the link to the first one will be paused until you decide to reactivate or remove it. You can only switch between the two linked accounts by logging in via the mobile app.
