Welcome to FT.
Are you trying to
transfer your UR to someone else's airline account or are you trying to
combine your UR with that person's Chase UR acct?
Is the AU a member of your household (same address)?
Please read the wikipost in this thread:
https://www.flyertalk.com/forum/chas...solidated.html There is a difference between "combining" and "transferring". There is also a link in the wikipost to a thread on "transferring".
