Several of the nation’s biggest airlines, including American and United... notified the U.S. government... that they wished to have no part in transporting those children to detention centers after they were taken from their parents after crossing the U.S. southern border... Volaris, the low-cost Mexican airline, announced that it was going one step further. The carrier said it would offer free seats on its planes to reunite those children with their families in Mexico and Central America. “Since its founding, Volaris’ mission has been to unite families,” the airline said in a statement. “Families belong together and our commitment is to help them stay together to better build their future.”...  The airline has yet to be contacted by immigrant families to take advantage of the offer, but the carrier plans to spread its message over the next few weeks on social media, Volaris spokeswoman Ana Ambrosi said. Volaris, which operates out of Mexico, the U.S., Costa Rica, El Salvador and Guatemala, has already contacted Mexico’s Foreign Ministry to offer its help.
