The internet is up in arms about what United Airlines did to two young girls. The girls along with an adult were flying on the airline and wearing leggings. One of the other passengers overhead the gate agent telling the girls that they couldn't fly in what they were wearing. The trio stayed at the airport to make other travel plans. The passenger that overheard the conversation tweeted her frustration at United. United later explained that the three were traveling as friends of a United Airlines employee and therefore had to abide by a professional dress code. Nonetheless, the internet was not happy.
