Royal Dutch Airline KLM apologized Sunday night for a tweet Mexico Soccer fans found offensive. After the Netherland's 2-1 victory over Mexico on Sunday during the World Cup, KLM tweeted a picture of an airport departures sign with a logo of a man with a sombrero and mustache under the heading, "Adios amigos!" After backlash on social media, the airline apologized saying "In the best of sportsmanship, we offer our heartfelt apologies to those who have been offended by the comment."
