Southwest Airlines canceled several hundred more flights Monday following a weekend of major disruptions that it blamed on bad weather and air traffic control issues. Both the company and its pilots' union denied reports of a sickout to protest mandatory COVID-19 vaccinations.

Southwest canceled more than 360 flights — 10% of its schedule for the day — on Monday, and more than 800 others were delayed, according to the FlightAware tracking service.

Shares of Southwest Airlines Co. briefly fell more than 4% before a partial recovery; they were down 3% by afternoon.

The widespread disruptions began shortly after asked a federal court on Friday to block the airline's order that all employees get vaccinated against COVID-19. The union said it doesn't oppose vaccination, but it argued in its filing that Southwest must negotiate before taking such a step.

The union denied reports that pilots were conducting a sickout or slowdown to protest the vaccine mandate, saying it “has not authorized, and will not condone, any job action.”

The pilots association offered another explanation: It said Southwest’s operation “has become brittle and subject to massive failures under the slightest pressure” because of a lack of support from the company. The union complained about the “already strained relationship” between it and the company.

Airlines persuaded thousands of workers to take leaves of absence during the pandemic. Unions at Southwest and American have argued that management was too slow to bring pilots back, leaving them short-handed.

Alan Kasher, Southwest's executive vice president of daily operations, said the airline was staffed for the weekend but got tripped up by air-traffic control issues and bad weather in Florida and couldn't recover quickly. Because of cutbacks during the pandemic, he noted the airline has fewer flights to accommodate stranded passengers.

“The weekend challenges were not a result of Southwest employee demonstrations,” said airline spokesman Chris Mainz.

The White House has pushed airlines to adopt vaccine mandates because they are federal contractors — they get paid by the Defense Department to operate flights, including those that carried Afghanistan refugees to the U.S. this summer.

United Airlines was the first major U.S. carrier to announce a vaccination requirement. Southwest had remained silent even after President Joe Biden announced his order for federal contractors and large employers. Finally last week, Southwest told employees they must be fully vaccinated by Dec. 8 to keep their jobs. Workers can ask to skip the shots for medical or religious reasons.

Meanwhile, the Federal Aviation Administration acknowledged delays in part of Florida on Friday but pushed back against Southwest's air-traffic control explanation. The FAA said Sunday that “some airlines” were experiencing problems because of planes and crews being out of position. Southwest was the only airline to report such a large percentage of canceled and delayed flights over the weekend.

Savanthi Syth, an airlines analyst for Raymond James, said the weekend problems will increase Southwest’ costs and worsen the company’s strained relations with unions.

Southwest has struggled all summer with high numbers of delayed and canceled flights. In August, it announced it was trimming its September schedule by 27 flights a day, or less than 1%, and 162 flights a day, or 4.5% of the schedule, from early October through Nov. 5.

New York Times, after Trump post, says it won’t be deterred from writing about his health
The New York Times and President Donald Trump are fighting again. The news outlet said Wednesday it won't be deterred by Trump's “false and inflammatory language” from writing about the 79-year-old president's health. The Times has done a handful of stories on that topic recently, including an opinion column that said Trump is “starting to give President Joe Biden vibes.” In a Truth Social post, Trump said it might be treasonous for outlets like the Times to do “FAKE” reports about his health and "we should do something about it.” The Republican president already has a pending lawsuit against the newspaper for its past reports on his finances.

What to know about changes to Disney parks’ disability policies
Disney's changes to a program for disabled visitors are facing challenges in federal court and through a shareholder proposal. The Disability Access Service program, which allows disabled visitors to skip long lines, was overhauled last year. Disney now mostly limits the program to those with developmental disabilities like autism who have difficulty waiting in lines. The changes have sparked criticism from some disability advocates. A shareholder proposal submitted by disability advocates calls for an independent review of Disney's disability policies. Disney plans to block this proposal, claiming it's misleading. It's the latest struggle by Disney to accommodate disabled visitors while stopping past abuses by some theme park guests.
