PHILADELPHIA (CBS) — Some customers waiting to fly to their Christmas destination are scrambling to book another flight. United and Delta Airlines are canceling dozens of Christmas Eve flights.

There have been 18 total flight delays and three flight cancellations so far at the Philadelphia International Airport on Friday.

United says the spike in omicron cases this week is having a direct impact on its flight crews and the people who run its operations.

Delta blames its cancellations on omicron and other issues as well.
