Airspace users can set up a recurrent credit card payment instruction in CEFA. In this case, the credit card will be charged automatically according to the Credit Card payment calendar. For each billing period, there are two scheduled payment runs, referred to as "Run 1" and "Run 2" in the payment calendar. These runs ensure that payments are processed before the due date.
Additionally, the calendar displays the billing periods and payment dates, making it easier for airspace users to manage their payment instructions in case they prefer to give ad hoc payment instructions
