以后填表用 U or X 代替 male and female
American Airlines will now allow travelers to choose non-binary gender options during the booking process.
Customers can now designate “U” or “X” for their gender instead of male or female, American Airlines confirmed in a statement to The Hill.
"We recently completed a system update to offer non-binary gender selections. Taking care of our customers and team members is what we do, and we are glad to be able to better accommodate the gender preferences of our travelers and team members," the airline said in the statement.
