Lucky writes about his experience opening a Chase checking account for 25,000 miles. It just takes a $100 deposit and 5 debit card transactions run as a credit card (i.e. without use of a PIN) to earn the 25,000 miles. Next he’ll go open a business account the same way, bam 50,000 miles. And this can be done each year, apparently.
Believe it or not I still haven’t done this, I don’t have a nearby Chase branch although presumably I could go into one and open an account when I’m in a city where a physical branch is convenient. Sadly this is not a promotion for an online account.
