An outage that affected United Continental's computer systems on 28 August had minimal impact on the airline's bookings, says its chief executive Jeff Smisek.
Calling it a "connectivity issue", Smisek says today at the Deutsche Bank Aviation & Transportation conference in New York that the impact on bookings will be "trivial".
"It was not a crash of the computer system, it was a connectivity issue," he says, tracing the problem to a data centre of the airline's in Charlotte, North Carolina.
"A large switch failed. We continued connectivity with our GDSs, but we lost connectivity to our airports and to our website," adds Smisek, who says the system was out for more than two hours.
The airline is working with the supplier of the part that failed to determine what happened, he says.
The outage on 28 August resulted in several flights being grounded at airports, and led to further questions over United Continental's reliability that it has faced following integration issues since the merger.
Smisek acknowledges that the airline's growth of the corporate travel market has been less than what it had anticipated due to these integration issues, but he believes they are "transient". "We are quite bullish about our future," he says.
