I had the exact same experience (didn’t downgrade myself thouh as I was in coach) a few years ago.
Super nice, much older, female flight attendant that literally woke me up when she walked by my seat from the smell. I have moderate allergies and usually it’s not a problem.. this was on another level. I wrote to AA while on the flight. This was their response:

Dear Mr. XXXXXXXX
Thank you for contacting Customer Relations.
We understand your inquiry about the issue of exposure to perfume/cologne or any chemical odors contained in other grooming/hygiene products. We do allow our flight crew to wear perfume/cologne. However, during flight attendant training, we further define this particular grooming item with the indication that the fragrance should not be overpowering. Of course, there is some subjectivity related to the "strength" of such odors.
In view of your comments, we've shared the details of your experience with the appropriate management personnel.
Mr. XXXXXXX, sorry for the inconvenience. We hope to welcome you aboard soon.
Sincerely,
xxxxxx xxxxxx
