Travel delays caused by Southwest Airlines glitch

The airline warned passengers flying Monday to arrive two hours early and print boarding passes before coming to the airport.

Southwest Airlines now expects Monday to be a normal operating day. Intermittent performance issues continue impacting our in-airport Customer Service technology systems and across our online platforms (Southwest.com, Southwest Mobile App and site).

Southwest Airlines says the technical problem that delayed hundreds of flights on Sunday has been solved.

The tweet said that all operations at BWI were almost back to normal with close to no delays and lines of passengers were diminishing.

Prior to the news on Monday mornings that the glitch was resolved, Southwest said it remained working to have the problem fixed.

A Southwest Airlines ticketing computer failure caused long lines at LAX. Teams worked throughout the night in advance of our first departures to ensure the smoothest operation of our originating and later flights. “If everyone had done that, it would’ve saved so much time”, Schultz said, according to the Chicago Tribune. Southwest Airlines announced that a “technical glitch” was casing the problems in the company’s passenger processing system, and technicians were trying to solve the problem. The Dallas-based airline said Monday that Southwest is still working to deliver bags and get delayed or displaced customers into open seats.

As of 5 p.m. ET on Sunday, 450 flights were delayed out of approximately 3600 flights scheduled to operate. Southwest Airlines On-Time Arrivals: 83.1% Denied Boardings: 0.84 per 1,000 passengers Mishandled Baggage: 3.08 per 1,000 passengers Customer Complaints: 0.25 per 1,000 passengers.

The delays follow several high-profile computer problems faced by USA airlines in recent months.
