Direct Deposit and Automatic Payments

Direct Deposit and Automatic Payments

To ensure there are no interruptions to any of your direct deposits or automatic transactions, we are currently building a cross reference for any ACH transactions.  With this, you should not need to do anything regarding direct deposit.  Please update your information with any new vendor(s) or company debiting or depositing transaction(s) to or from your Day Air Credit Union account.

Your current Triangle Credit Union direct deposits and automatic payments will be directed to your new account at Day Air Credit Union after May 1, 2017.   If you have any direct transfers from these deposits to other accounts or loans, these transfers will need to be set up again.  You can do this in online banking or call us at 937-643-2160.

  • After May 1, 2017, please use your Day Air account number and the Day Air Credit Union routing number when setting up any NEW direct deposit or automatic payment information.
  • Day Air Credit Union routing number: 242277808


Day Air Credit Union Account Number

Your new Day Air Credit Union account number will be similar to your current Triangle account number.  We will be adding a 1 and 0’s to your account number to make it a 9 digit number.

Example:  Triangle # = 123410, your Day Air # will be 100123410.

If you already have a 9 digit account number with Triangle, your account number will remain the same.

  • Your direct deposits and automatic payments will be directed to your new account at Day Air Credit Union after May 1, 2017.
  • You will need to reference your Day Air Credit Union account number and routing number when setting up any NEW direct deposits or automatic payments after May 1, 2017.

If you have any automatic transactions associated with your Triangle ATM/Debit Card, please update them with your new Day Air Credit Union Visa Debit Card number on May 1, 2017 to avoid any late payments or disruption to your service.
