The fadeout of flights under the US Airways banner is expected to start in July and take around 90 days, according to the Associated Press. “It’s absolutely critical because it’s really the core system for almost every customer-facing transaction that happens at the airline,” said Maya Leibman, the chief information officer for parent American Airlines Group AAL , according to the AP. The merging of bookings systems was a huge sticking point for United Airlines and Continental after their merger in 2012. The two companies now form United Continental UAL . US Airways has been flying for over 75 years.
