About FlightStats On-Time Performance ReportsThese on-time performance reports for worldwide carriers and airports are generated from FlightStats Analytics. We track the performance of over 150,000 flights per day, archive the data for analysis and publication, and provide real time flight status to millions of travelers world wide each day.

In contrast to the US Bureau of Transportation Statistics (BTS) on on-time performance which are filed with the BTS by the largest US airlines, we gather it ourselves in real time and archive the data for analysis and reporting. This enables us to cover a larger list of airlines and airports and to issue reports within a few days of the end of the reporting month.

• BTS reports only on US airlines and airports. FlightStats gathers data world-wide • BTS airline performance reports are based upon data reported by 19 US airlines, 18 of which constitute

1% or more of total domestic scheduled-service passenger revenues. FlightStats reports cover 45 US airlines and are based upon data gather in real time from a variety of sources including the US FAA, airlines reservation systems, direct feeds from airlines and airports.

• BTS US airport performance reports are based upon information provided by the 32 U.S. airports that account for at least 1 percent of the nation's total domestic scheduled-service passenger enplanements. FlightStats equivalent reports are based upon archived real-time data covering the top 40 (i.e. busiest) North American airports.

• Both BTS and FlightStats reports include information on the percentage of flights that arrived on time, were cancelled, were diverted. FlightStats breaks down the delays into 3 categories - late (15-29 minutes late at the gate), very late (30-44 minutes), and excessive (> 44 minutes). BTS simply reports that a flight is late (15 minutes or more).

• FlightStats has more current data based upon real-time reporting. BTS data is published approximately 5 weeks after the close of a month as it relies on the airlines to file historical reports.

• BTS also reports on baggage issues, passenger numbers, customer complaints and the causes of flight delays. FlightStats does not.
