So I booked an international flight for 1700. I redeemed 100,0000 in pts from my reserve and paid the remaining 200 on my reserve card through the Chase Ultimate rewards portal.

American Airlines has a free change waiver for my flight due to corona. This flight has now dropped to 1200 bucks. When I logged into AA through my booking ID , I rebooked the same flight and was due a 500 dollar refund

AA said they have refunded the credit card used for original payment. Since I booked this through Ultimate rewards, they used their credit card for the purchase (different account than my personal card)

My question is - How can I get this refund transferred to my personal card? Also since I booked originally with pts and cash will I be refunded 200 (cash that I originally paid) + 45,0000 pts (remaining 300x1.5) or will they just transfer the 500 credit directly to me? Will i have any issue receiving this refund from chase per their terms? Thank you
