SkyWest attributed recent cancellations to both "ongoing weather challenges in major hubs and crew availability as a result of elevated COVID cases and quarantines, with the majority being weather."
"If you're traveling within the next week, chances are it's still going to be a very, very uneven, perhaps even chaotic operating environment for airlines," Harteveldt said. "My hope is that within the next week, because of the new guidelines posted by the CDC that say employees who are fully vaccinated and asymptomatic can return to work if they feel well enough to do so, we will start to see the number of cancellations go down."
Both Tajer and independent travel industry analyst Robert Mann noted that airlines have been known to inadvertently incentivize people to work when they don't feel well, with policies like paying flight attendants triple pay to show up during busy periods or taking away previously earned overtime pay for pilots who get sick and call out for regular shifts.
