OK first shot AA. Applied online for Visa - still waiting for reply and over the phone for Amex which got approved immediately.
Hoping that after they will send me targeted offer for the checking account which would add additional 30-40k as other flyers report.

Also thinking about Continental 50k and UA 30k which, as I read, would merge once the merger process is completed. Is this true?
The only concern I have is applying for cards in the same bank (both are from Chase).
Should I be worried about this?
Also thinking about SPG Amex, but here the $15k spend is my concern.
What about 45k Delta Amex? (considering this because already have ~19k with Delta).
