A computer glitch at Southwest Airlines caused delays and thousands of cancellations and the effects were still being felt Friday at airports across the U.S.
More than 250 Southwest flights were canceled Friday which is routinely a very busy travel day for the airline.
"We recommend customers who have flexibility explore rebooking on alternate dates beyond Sunday," a Southwest spokesperson told NBC 7.
To help, the airline is offering a two-week window for travelers to rebook travel at the original fare, at no additional cost.
"We extend a heartfelt apology to our employees and our customers who are inconvenienced by the disruption in service. We appreciate their patience as we continue our work to make this right," the airline spokesperson said in a written release.

In San Diego alone, Southwest cancelled 53 flights and had more than 140 delays.
