Ike: Thank you! So best bet would be opening all three Amexes on the same day? I see the spends are relatively low on the MR cards, and I could then decide later where to transfer them to (i.e., possibly BA and then use those miles to fly on AA metal to avoid surcharges - if it works like that). And apply for SPG on the same day because it's also an Amex.

For the business Amex, you just want to do sole prop using your own name, correct?

Silly question, we're moving in 14 days.....I'm guessing CCs don't forward in the mail, right? Not sure CCs would arrive before we actually leave, especially with the holiday.

15K spend on SPG....in 6 months? That might be tough on both cards since we typically average 3K total/month.
