PayPal is a safe, easy way to pay. The service allows anyone to pay in any way they prefer, including through credit cards, bank accounts, buyer credit or account balances, without sharing financial information. Before using PayPal, you need to register with them, and you need to register a method of payment with them, such as a credit or debit card.
When booking online at emirates.com and selecting the PayPal option, you will be sent to the PayPal website, where you will need to log-on and select one of the payment methods that you have registered with them in order to pay. PayPal will process your payment, and you will then be taken back to emirates.com, where your booking confirmation and e-tickets will be given. PayPal provides payment to Emirates on your behalf, and your payment method details are not given to Emirates.
