Hopefully this helps some folks, I was charged for drinks on a flight last Thursday. I asked the FA if the drinks were included in MCE now, she said they were but I wasn't sitting in MCE (I was in the exit row, with an MCE placard above it), then followed that by saying it was only rolled out on certain planes. I shot a polite email out to customer service on Friday and got this response:
"I am so sorry you were told that you did not get free drinks in your MCE seat. That information was incorrect.
I have reported the flight attendants on
(flight#) to Flight Service management so they can make sure they are updated on the new perks of MCE. On all MCE seats with FULL beverage service passengers get free drinks (beer, wine and spirits) starting June 5, 2018. As an apology and gesture of goodwill for this I have added 2,500 bonus miles to you AAdvantage account.
(name), thank you for bringing this to our attention and we look forward to flying with you again soon.
Sincerely,
(name)
Customer Relations

I asked about getting a refund for the purchased drinks, but she kind of ignored that part of my original email, the points balance it out a bit though.
