 My son and I are at United Airlines waiting for our flight from San Francisco to Austin. And the flight attendant has denied access to us because he said that I made a derogatory comment about one of the flight attendants because I didn't use their right pronoun. Now they are forbidding us to get on the plane. I am with my son. He is 25 pounds. I've been carrying him for about 30 minutes. They denied us boarding priority.
