The battle continues in the “Friendly Skies” after two girls attempting to fly to Minneapolis-St. Paul International were kept off a United jet on Sunday. There were three young teens who were stopped at the gate in Denver and told to change or put a dress on over their leggings. A witness said one of the girls had a dress and put it on over her outfit. The other two girls had to take a later flight. United officials clarified the airline’s stance, saying the girls were traveling with employee passes, which require a specific dress code. The incident sparked a major backlash on Twitter.
