Took me over a month to receive a reply as a PM.
Had a flight cancel on AA due to mx issue last Thr 7/7. Emailed them from the airport in the morning and recd an apology and had 7500 AA miles in my account THREE HOURS later with NO STATUS on AA.
AA answering no status member emails within hours while DL is taking WEEKS to get back to Medallions...yet another sign of how pitiful DL's guest service has become.
