I don't believe there is a way to make payments on a flight unless you are doing group travel then I think you could do payments but for personal travel like 1-8 people you would have to pay in full i have seen where you can get months to pay if you get a credit card or line of credit from PayPal though should you want to do that not sure how that works completely but I have seen that when booking flights or buying things on eBay using PayPal Hope this helps Blake
