700 Southwest flights canceled by computer glitch, fallout expected to last a week

CHICAGO -- A computer outage Wednesday temporarily halts Southwest Airlines service across the country.

Flights were held up while the airline worked to fix the problem.

For about three hours, customers couldn't buy tickets, check-in for flights or check their flight status online.

700 flights were canceled as a result and more than 600 were delayed.

Southwest customers were faced with very long lines at Chicago's Midway Airport this morning due to the computer glitch.

Southwest has offered countless apologies over social media, and tweeted a video Wednesday to explain the problem and give an update:

Southwest says the system is still not fully functional this morning, but systems are gradually coming back online. The airline hopes to have the situation completely corrected by the end of today.

Passengers traveling today and Friday are being warned to check their flight status online.
