The grounded flights are causing massive delays and cancellations during a weekend when an estimated 10 million passengers are expected to fly throughout the country this holiday weekend. In LAX alone over 540,000 people are expected to catch their flights this weekend. On Saturday, at LAX there have been 280 delays and 134 cancellations.

Airlines are attributing the cancelations and delays to winter weather and the highly contagious Omicron variant which has infected many airport workers, with over 1,700 TSA agents out sick with COVID-19.
