Question: I have flight credits from my canceled May 2020 flight. I originally paid cash for the four of us for roundtrip flights. As the pandemic first started to happen and people got nervous about flying, my flights cost decreased three times and I rebooked and got credits. Then, ultimately I had to cancel and got credit for the balance. So, now we have the total amount of that original flight broken down into four credits. I see online that you can only use "three forms of payment" and one credit is considered a payment. So, my assumption is I can only use two credits and probably a credit card per reservation which means I leave two credits unused. If I book a one way flight instead of round trip, can I use two credits and credit card for each way and thereby use all my credits?
