Even though this does not relate to miles for deposit balance but another good option to get Aadvantage miles is UFBDIRECT. You can get 11000 miles in the first year and 5000 miles every year afterwards as follows.
Open new account. 1000 miles.
Set up direct deposit. 5000 miles after 3 deposits.
Sign up for online bill pay. 5000 miles after 12 months and then on every anniversary date.
I have been using them and am quite pleased with the service. Minimum balance to avoid fee is 200 dollars. Online billpay is free with direct deposit. It does not have to be payroll but has to be ACH. I simply transfer few hundered bucks every month from my brokerage account via ACH and is working fine. BTW, info about this is not found on AA.com. It can be found on King Gary's web site or simply UFBDIRECT.com.
