I suggest you hunt down Doug Parker's Email.
I had various issues a few years ago and sent him an Email, I doubt if he read my Email but he has a staff of people that are very much about customer loyalty and they respond within a day.
If you know anything about IT, you should be able to figure out his Email. Good luck
I have 3 million miles, I retired last year and did not meet EXP this year and miss the perks now being a lowly Platinum.
