The request for actors, which was sent out by another company, specified it wanted "nobody dark skinned" and only those with "white skin."
Aeromexico said in a statement, "We offer our deepest apology and reaffirm our respect for all people, without regard to their gender, language, religion or skin colour."
The search for actors also said it did not want anyone with blond hair or blue eyes.
Palaeontologists have discovered the remains of a 72 million-year-old dinosaur tail in a desert in northern Mexico.
The 16-foot tail was the first ever found in Mexico according to Francisco Aguilar, the director of the National Institute for Anthropology and History.
The team spent 20 days in the desert slowly lifting a sedimentary rock, before finding the 50 vertebrae of the tail completely intact.
The fossil was identified as a hadrosaur or a duck-billed dinosaur.
Palaeontologists said the tail probably made up half of the dinosaur's overall length.
Mexican authorities are investigating the death of at least 250 stingrays found on a beach off the Gulf coast state of Veracruz.

The Mexican government says it has captured the leader of the Zetas drug cartel, delivering a boost to President Enrique Pena Nieto in his fight against violent crime.
Miguel Angel Trevino, 40, known as Z-40, was captured early on Monday by Mexican Marines near the northern city of Nuevo Laredo on the US border, a government spokesman told reporters.
Many of the worst atrocities in the drug war have been blamed on the Zetas, including the massacre of dozens of migrants in northern Mexico in 2010 and the dumping of 49 decapitated bodies near the city of Monterrey last year.
The US State Department had offered a reward of up to $5m (£3.3m) for information leading to Trevino's capture.
