More than two dozen flights were canceled [Tuesday] at the Las Vegas airport, with more than 1,000 flights scrubbed nationwide as airlines struggle with COVID-induced staff shortages and bad weather.

Joe Rajchel, a spokesman for Harry Reid International Airport, said that as of noon, 27 flights were called off — 16 arrivals and 11 departures.

“We’re seeing the convergence of many different factors,” Rajchel said, citing weather and the coronavirus. “The airlines don’t give us a reason for each individual cancellation. It’s one big network, once some cancellations start, it’s like a domino effect.”

Flight delays and cancellations tied to staffing shortages have been common this year.
