There were very few canceled flights in the US last year

According to the ministry, the 0.8 percent cancellation rate was even better during holidays, even though passenger numbers were at a record high. That's a big difference from a year ago, when Southwest Airlines canceled flights due to bitterly cold weather. Ultimately, the cancellation rate for the holiday season was 8.2 percent.

President Joe Biden's administration plans to introduce regulations to compensate for long delays and cancellations if they are attributed to airline policies. Meanwhile, the government is also trying to force airlines to fly as scheduled. “We've put a lot of pressure on the airlines,” Transportation Secretary Pete Buttigieg said Wednesday on CNBC.

Airlines for America, a trade association representing airlines such as American Airlines, Delta Airlines, United Airlines and Southwest Airlines, reported that US airlines hit their targets 83.7 percent of the time in December. According to the trade association, 99.6 percent of flights were fully completed last month.
