摘要：	Several snowstorms in the Northeast, Midwest, and Southeast during February 2010 disrupted air travel not only at airports blanketed with snow but at airports across the United States and its territories. Altogether, more than 20,000 flights, or 4.2 percent of all flights scheduled during the month, were canceled due to weather. This was the highest weather cancellation rate for any month since the Bureau of Transportation Statistics (BTS) began collecting data on the extent and causes of cancellations in June 2003. The national ramifications can be seen in figure 1, which shows the origin and destination for air travel segments2 (originating from a major airport) canceled because of weather on Feb. 10, 2010 the day with the most scheduled flight disruptions in February. From the 35 major airports, all flights were canceled on 510 segments, accounting for 20 percent of all scheduled departures (2,350 flights) from the 35 airports. All flight segments departing from two major airports Baltimore Washington (BWI) and Washington Reagan (DCA), and two small airports Long Island-Islip (ISP) and Atlantic City (ACY) were canceled due to weather. In looking at the impacts of weather on on-time airline performance in February 2010, this report uses BTS Airline On-Time Performance data. Analysis shows: February 2010 had the greatest proportion of weather-related cancellations on record, with 4.2 percent of flights canceled (20,206 flights). The previous record was 2.8 percent (15,872 flights) in February 2007. On the peak day, February 10, 23 percent of all scheduled flights (3,932 flights) were canceled nationwide due mainly to the near or complete closure of several large Northeastern hub airports. Cancellations from storms over the entire month are estimated to have cost $80100 million.
