description: This report contains airline operating statistics for large certificated air carriers based on data reported to U.S. Department of Transportation (DOT) by carriers that hold a certificate issued under Section 401 of the Federal Aviation Act of 1958 and that operate aircraft designed for maximum passenger seating capacity of more than 60 seats or a maximum payload of more than 18,000 pounds or that conduct international operations. The data consist of passenger and cargo capacities and traffic actually carried by carrier entity and class of service in both scheduled and nonscheduled service for the most recent month and 12-month period and similar data for like periods in the previous year.

The total size of the zip file is 1 MB. This dataset was originally preserved in RTF format. The .rtf file type is used for documents written in Rich Text Format, a text format with some very basic formatting preserved. The .rtf format stores data in plain ASCII text file with additional formatting commands somewhat similar to HTML files (for more information on .rtf files and software, please visit https://www.file-extensions.org/rtf-file-extension). The document has been curated and preserved by National Transportation Library Data Services to include CSV and XLSX copies of the data for preservation and improved access/use by the public.  The .xlsx and .xls file types are Microsoft Excel files, which can be opened with Excel, and other free available spreadsheet software, such as OpenRefine. The .csv, Comma Separated Value, file is a simple format that is designed for a database table and supported by many applications. The .csv file is often used for moving tabular data between two different computer programs, due to its open format. The most common software used to open .csv files are Microsoft Excel and RecordEditor, (for more information on .csv files and software, please visit https://www.file-extensions.org/csv-file-extension). The zip file also includes a Markdown README document that contains information about the dataset, including its rights, variables, and description. The file extension .md is among others related to texts and source codes in Markdown markup language. Markdown is a lightweight markup language, to write using an easy-to-read, easy-to-write plain text format, then convert it to structurally valid XHTML (or HTML) (for more information on .md files and software, please visit https://www.file-extensions.org/md-file-extension). The zip also contains a DCAT-US Version 1.1 metadata file in the JSON format, as required for all federally funded and produced datasets. File extension .json is associated to JavaScript Object Notation file format, a lightweight, text-based, language-independent data interchange format. JSON defines a small set of formatting rules for the portable representation of structured data. It is used by various applications as alternative option to XML file format. The data in a json file are stored in simple text file format and the content is viewable in any simple text editor (for more information on .json files and software, please visit https://www.file-extensions.org/json-file-extension).
