Have done the referral for her and got the miles last year.
15K for me and 30K for her. Then canceled her card.
Need to build my account back up as I just cashed in most of my UA miles.
We both have DL AMEX and AA Mastercards which all go to my accounts.
Use DL Amex for everything we can, but need a Visa card for UA instead of building more on AA. She uses that when she can't use Amex. I have about 135K in AA but down to 2K UA. I want to work on building it back up.
