Overall, the carrier has canceled about 1,850 flights since the problem first surfaced.
“We are continuing our work to reposition displaced crews and aircraft as a result of Wednesday's technology issues,” Southwest spokeswoman Brandy King said in a Friday morning e-mail to Today in the Sky. “We have more than 250 systemwide cancellations today, as we continue our recovery efforts.”


The Wednesday glitch knocked the carrier's website offline for several hours and delayed flights around the country for much of Wednesday afternoon and evening.
Southwest said it has fixed the problem, which forced it to cancel 700 flights on Wednesday and another 900 Thursday. Hundreds of additional flights have suffered delays during the outage and in the related recovery. The airline operates about 3,900 daily flights this time of the year.
Friday's passengers faced the prospect of more disruptions as Southwest continued its effort to get crews and planes back into position for a normal schedule. Southwest said on Thursday that it hoped for normal operations by Friday, a target the carrier clearly has missed.
A rush of customers calling to rebook appeared to have put a strain on Southwest's reservations lines.
