One can pay for your flight during the 72 hours time period with your booking number and name.
One can simply hold your Emirates tickets after choosing the hold my fare option at the payment page whenever you reach the payment page after entering your flight details. One has to be required to pay your reservation fee by entering your card details and you can only use this option for the economy class on Emirates.
