Where can I see how many miles I redeemed for a flight for a future reservation? On the desktop, I went into my activity and it only shows the date the reservation was made and the city pair. It doesn’t show confirmation number or the actual date of the flight. Is it better on the app?

I have made multiple reservations for the same city pairs and can’t match them up. I suppose I could go back to the confirmation emails but there should be an easier way.
