Summary Airline On-Time Performance Query

Contains summarized on-time performance data for all airlines having one percent or more of the domestic scheduled passenger revenues. There are over 150 million individual flight records from October 1987 to August 2022 that may be selected and grouped by flight date, carrier, flight number, origin, destination, frequency, and flight delay.

This query will return summary Comet information for each grouping consisting of "Total Flights", "% Flights On Time", "% Flights Late", "% Flights Canceled", "% Flights Diverted", "Average Departure Delay", and "Average Arrival Delay". For more information about the query's results, see the definitions of the summary fields. General query help is available. In addition, detailed help is provided for a data item when it is displayed as a link.

Depending on the query selection criteria, grouping, and other activity on the system, it could take up to 2 minutes to return the results. A maximum of one years's data can be selected for each request.

Individual flight segment detail airline on-time performance data can be found at the Airline On-time Performance - Detail Query.

See the Overview of all of the reports and queries available for Airline Industry statistics, including on-time performance, capacity and utilization, fuel usage, profit and loss, and expenses.

General Help

The fields can be used to select and group the data items to be returned, select the data to return, choose the output format, and to reset the fields to their default values. For best results, start with the fewest values and broadest criteria ( for instance "contains" instead of "equals"). If there are too many results, use more values and narrower criteria. Depending on the criteria used, it could take as much as 2 minutes to return the results of the query.
Hints to get results
Criteria values restrict the results to match all the values entered.
All data is returned when no criteria values are used.
If there are too many results, enter more criteria.
If there are not enough results use only one criteria value, use "contains" with a minimum number of characters or use broad ranges until results are returned.
Spelling, punctuation, and spaces can be inconsistant in any text such as names, addresses, serial numbers, etc.

Group By
Click on the boxes to display and group the data items to be returned.

Criteria
One and only one may be chosen per data item and take effect if any entries are made into the "value(s)" column. Comparisons are not case sensitive and the data item need not be selected for display to be used as criteria. The selections are:
Equal (default)

Not Equal
Does not match the specified value. One and only value may be entered.
Equal or Less

Equal or More
