The United States Transportation Department’s Office of Inspector General has released a report stating that the government needs more in-depth data on flight cancelation sand delays.
From 2000 to 2012, cancelations dropped by 56 percent at major airports, and delays dropped by 33 percent. These decreases can be attributed to changes in air traffic control procedures, improvements to airport infrastructure, mild weather, and a decline in the number of scheduled flights.
These numbers may not be as accurate as possible, though, because not all carriers must report delays. Only 76 percent have reported. Further, almost 40 percent of the reported delays were unexplained.
