Comedian Sarah Silverman tweeted that she would change her United flight bookings to other airlines for a tour next month because of the leggings issue. While using the free or heavily discounted travel passes, “all employees and pass riders are considered representatives of United,” the airline said in its post. “We care about the way we present ourselves to you, our customers.”However, Guerin said that people who use employee travel passes are not outwardly identifiable to the public.
