UPDATE: Southwest Airlines says it's fixed the technology problems that delayed hundreds of flights Sunday and that it expects a normal day of operations.
If you plan to head to the airport on Monday, you could see long lines and possible delays. Southwest Airlines is dealing with a massive technology glitch and a lot of frustration.
Hundreds of Southwest Airlines flights were hit with turbulence after that glitch and the problems apparently still aren't fixed. This could cause delays on Monday.
From Los Angeles, to Chicago, to Denver and Baltimore, lines at the Southwest desk were long. Technical problems forced staff to check in passengers manually at dozens of airports on Sunday.
The delays impacted their baggage system and even the outside lines at curbside check-in. Southwest is working to fix the problem but the airline does not know what caused the issue.
Here is what you need to know if you are flying Southwest on Monday. The airline warns passengers to arrive two hours early and print your boarding passes before coming to the airport.
