A US Airways flight attendant was found strangled today in his hotel room in Mexico City, the airline’s flight attendant union said.

The death of Nick Aaronson of Phoenix was being investigated and it did not appear that there was a safety breach at the hotel, according to a statement on the AFA US Airways MEC website.

Aaronson was found lying unconscious, face down beside the bed at the Hilton Hotel, with his hands bound behind him and a belt around his neck, according to a report by NoticiasMexico.com.mx, ABC affiliate KNXV-TV in Phoenix reported.

US Airways spokeswoman Tina Swail told KNXV-TV that Aaronson’s family has been notified of his death.

Deborah Volpe, president of the Association of Flight Attendants Council 66, told The Arizona Republic that Aaronson was “very popular” and “very loved” by co-workers.
