 She apparently referred to the gate agent as sir, though the agent identifies as a woman. United Airlines claims the woman and her family were prohibited from boarding due to a discrepancy over too many carry-on items, though the mom begs to differ. You know, we may never get the truth behind this debacle, but if the passenger really was booted for misgendering, I wouldn't be surprised. Who can keep up with all these pronouns and trans terminologies these days? This is utterly and absolutely ridiculous.
