Delta Airlines canceled about 100 flights on Easter Sunday and the company says several factors were to blame.
The Atlanta-based airline says staffing issues related to employee vaccinations and pilots returning to active status are part of the reason.
The cancellations come after a record-setting weekend for air travel during the pandemic.
On Friday alone there was a new pandemic-era travel record set with more nearly 1.6 million passengers traveling across the U.S.
Delta says it was able to re-book most of the passengers on other flights as well as resorting to putting some in middle seats.
