Waris Ahluwalia's trip to Mexico started out as a thrilling visit to a contemporary art show. But now the actor, model and designer says he's stuck in Mexico City's airport because the country's largest airline wouldn't let him board a flight home. Ahluwalia, who is Sikh, says Aeromexico staff and security screeners Monday told him to buy a ticket on a different airline after he refused to remove the turban he wears as part of his faith. "I was upset, I had anxiety, I was shaking, I did not speak," Ahluwalia said. "And then I realized, clearly, they have not been trained properly. I knew yelling will not do anything. It is about education and the policy." And so, days after he posted about fresh papayas and famed artist Frida Kahlo, Ahluwalia started sharing photos about his security screening. Ahluwalia -- whose acting career has included roles in "The Grand Budapest Hotel," "The Darjeeling Limited" and "Inside Man" -- drew attention to his plight on social media, posting a photo of what he said was his cancelled plane ticket.<br/>A spokesman for the airline said that Ahluwalia "was asked to submit to a screening and inspection before boarding, in strict compliance with TSA protocol." "We have offered the passenger (two) alternatives to reach his destination as soon as possible," spokesman Amilcar Olivares said. "We sincerely regret any inconvenience caused by this incident." Ahluwalia says the airline changed its tune after he made the situation public and acknowledges they've offered him the chance to get on other flights. But he says he won't board a plane back to New York until the airline makes a public apology and airport security personnel get Sikh awareness training and better training on how to screen passengers with religious headwear.<br/>
