Today I received a Bank of America checking account offer for 25,000 Alaska Airlines miles if I open a new Bank of America Interest Checking or Bank of America Core Checking account before July 31, 2015. The offer also mentions you must receive at least two direct deposits, each of $2,000 or more, within 90 days of opening the account.
The offer seems to be targeted to Bank of America customers with an Alaska Airlines Visa card. However, it seems that all you have to do is go to bankofamerica.com/alaskaoffer to sign up (Note: I do not receive any payment or compensation for you signing up). You may have to connect an Alaska Airlines Visa card to the account to verify that you are eligible.
