Dutch plane operator KLM has apologised for sending out a tweet from its official account making a joke of Mexico's defeat to the Netherlands at the World Cup.
Within minutes of Holland's 2-1 stoppage-time win, the firm published a picture of an airport departures sign under the heading Adios Amigos.
Next to the word Departures was a man with a moustache and sombrero.
The post went viral but was deleted shortly afterwards.
Mexican actor Gael Garcia Bernal tweeted to tell his two million-plus followers that he would never fly with the carrier again and hundreds of other people complained.
"It was meant to be a joke but there was too much negative reaction," said KLM spokeswoman Lisette Ebeling Koning.
She added that the airline never intended to offend Mexicans, which it serves via a daily flight between Mexico City and Amsterdam.
KLM issued a formal apology late on Sunday.
"In the best of sportsmanship, we offer our heartfelt apologies to those who have been offended by the comment," said Marnix Fruitema, director general of KLM in North America.
Mexican national carrier AeroMexico broadcast its own response on Twitter in support of the country's football team under an arrivals sign.
"Thank you for this great championship," it said. "You've made us proud and we're waiting for you at home."
