Matthew blogs that American has matched Delta’s hefty bonuses out of St. Louis, Raleigh, Pittsburgh, and Nashville.

Here’s the offer, courtesy of Matthew with links to register:

Double EQMs and Triple RDMs from RDU, STL, PIT, and BNA

The offer runs through December 31st and trips must originate and terminate in the same city, which must be one of the four listed above. You’ll need to separately register for each city you want to earn bonuses from.

Flyertalk’s Wanaflyforless suggests a way to leverage these bonuses for nearly 12,000 qualifying miles per day at a cost of $386+tax.
