Year-end Cancellations Summary


Despite the mild weather conditions in December 2011, North American air travelers were more likely to have suffered from canceled flights in 2011 than in 2010. We counted 211,665 canceled flights (2.12% of scheduled flights) by the forty airlines we track monthly for this report in 2011. That is up substantially from 2010's total of 174,225 (1.78% of scheduled flights).

There is a link below to the full report for 2011 airlines and airports.

NB: FlightStats on-time performance calculations are based upon data collected from a variety of sources- both primary and secondary. Our coverage of any single airline's flights varies in percentage terms. In some cases, only secondary sources can be obtained that represent a subset of an airline's total flight operations. This is especially true for certain low-cost carriers, notably Easyjet and Southwest Airlines.

Therefore, the calculations represented here should, in general, be considered indicative of an airline's performance but not a definitive measure. We continue to work hard to fill in our coverage gaps. However, reaching 100% coverage will require the cooperation of some airlines that, at present, are unwilling to participate.
