Oct. 12 (UPI) -- Southwest Airlines canceled more flights on Tuesday, but fewer than it did over the previous three days, as the carrier tries to rebound from disruptions that have stained its performance record.
The airline apologized for the disruptions on Tuesday and said workers have been "working diligently to restore stability."
"Southwest extends a tremendous apology to our customers and employees for the flight cancellations and delays which occurred over the weekend and on Monday," the company said in a statement.
The carrier said last weekend that air traffic control issues and "disruptive weather" helped cause the delays and cancellations -- reasons that have been questioned by experts and federal regulators.
Southwest also said that scheduling and staffing cuts due to COVID-19 have made it difficult to return to normal operations.
"Unfortunately, it just takes a couple of days to get things back on track."
