"Shannon Watts, who overheard the discussion touched off a firestorm on social media with a series of tweets describing a policy she suggested was unfairly targeting women and girls" Sorry Snowflake, I flew on a Pass from my Sister (Delta) a number of years back. Boston to LA. No blue Jeans and the shirt must have a Collar. My luggage was ready checked. Fortunately I had slacks in the carry on, but had to rush to a souvenir shop to buy a "Cheers" Polo Shirt. It was the rules, or did Delta discrimination against my Lily white male ass, huh Snowflake ?
Delta may have lightened the rules, but I'm not sure.
And Delta is not the only company that does this. Some companies, if you fly on their private aircraft for personal reasons, you are still required to adhere to the dress code. The company does not have to let you fly on their nickel.
Note to snowflakes: Don’t like it? Pay for your own dang ticket.
