Aeroflot says that they're unable to open the system for a Korean Air flight, and Korean Air claims that they can't modify our reservation since it's booked through another airline. (We have the confirmation numbers appropriate to both airlines.)

Any thoughts on which airline would be able to allow us to select seats, and how to go about this? Thank you!!
