 More than one-third of Aeromexico's flights were delayed on Monday, and more than 30 were canceled, following the Mexican airline's migration to the Sabre technology platform on Sunday. The carrier notified passengers of the change last week, requesting that anyone traveling Sunday purchase tickets in advance and arrive three hours before scheduled domestic departures and four hours in advance for international flights. On Tuesday, the airline reported that operations were gradually returning to normal, but continued to recommend that passengers arrive at least three hours in advance of domestic flights. According to a statement issued by Aeromexico last week, the new platform will improve the "customer experience at all points of contact throughout the reservation, ticketing and check-in process."
