10,000 DL miles from MCI.
I had an MCI account that was receiving AA miles. Last week I switched to Verizon as soon as the period for the AA signup promotion had expired.
Tonight I received a call from an MCI telemarketer who first offered me 5,000 and then 10,000 miles to return to them. I tried to push her for more than the 10,000 miles but she wouldn't budge. When I told them that I didn't want AA miles, but instead wanted DL miles, she agreed immeadiately.
Guy's, if you are receiving miles from MCI, check your signup dates and when the bonus miles end. MCI is very aggressive at keeping customers.
