Kasra,
They won’t. It’s no longer a mask issue it’s a professional appearance issue that the airlines neither have the need nor desire to ammend.
While I understand your attachment to your beard (I was very fond of mine), my desire to fly and earn hundreds of thousands of dollars a year doing something I enjoy far outweighed my need for facial hair. But hey, to each their own. I hope you and your beard are very happy together

LOL I understand that’s why I shaved it too. I never thought I would do it but I love flying so much and it makes me so happy plus hopefully when I’m done with flight school the pay check would be a good addition too.
14d later and it’s still a hot topic. 
Mind boggling…

I am locking this thread. Beards are not permitted at most US airlines, there are no exceptions and the policies are not likely to change anytime soon.
