More Delays likely for Southwest Arilines

DALLAS (AP) — Southwest Airlines is warning passengers today to get ready for possible delays because of technical problems that began yesterday morning.

The airline is telling travelers to arrive two hours early and print their boarding passes before coming to the airport. Southwest says it's been using back-up systems around the country to check-in travelers who don't have boarding passes. About 450 flights were delayed yesterday.

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. Southwest is also asking customers to arrive at least two hours before their scheduled departures.

Southwest did not immediately respond to messages seeking details Sunday.
