Southwest Airlines says tech glitch causing flight delays nationwide

DALLAS (AP) — Southwest Airlines says technology issues have delayed some flights as airline employees have to process travelers manually as they arrive at airports.

At Los Angeles International Airport, several dozen people crowded the Southwest terminal, waiting to be issued hand-written tickets.

We found several flights impacted at Sea-Tac International Airport.

The company said that as of Sunday afternoon, about 450 flights set to operate on Sunday had been affected by short delays.

In a statement on its website, the Dallas-based airline said it's working on the technology issues and airport-based employees are helping customers with their individual itineraries:

"We’re continuing to experience intermittent technical issues on platforms, the Southwest Mobile app, and in our phone centers, as well as in airports across our system today. The issues are impacting website performance in creating new bookings and requiring us to process some Customers manually as they arrive for travel.

We’re asking Customers to arrive at least two hours prior to their scheduled departure to allow for additional processing time. We also advise Customers to utilize airport kiosks to print boarding passes and print bag tags when checking luggage."

Southwest did not immediately respond to messages seeking further details Sunday.
