MCI 25,000 mile code
 

The code for MCI 25,000 miles offer (5,000 per month)is Z25A when you call 800-272-7521. They explained this program just started 2 weeks ago and they don't know what the computer is going to do when existing customers change over - whether they will include the bonus miles you already received in the 25,000 or if one would receive 25,000 more. It seemed that chances were higher of starting fresh with your 25,000 mile count if you changed airlines. Offer ends May 13th.

I was able to get the "additional" miles as well....They have set up a specific number to handle existing MCI customers wanting to get the additional points 800-754-7076. The code above was correct.

Way to go Flyertalk! We beat them into submission!

it only took 5-6 calls, but the cust svc rep finally put in the request for an additional 14k miles to be posted. she seemed surprised that i got the mailing in PA. now, will the miles show up??
