Air Carrier Financial Statistics (Yellow Book) contains quarterly airline financial statistics obtained from carrier reports to DOT on BTS Form 41 financial schedules. Effective with a rule (ER-1297) adopted July 1982, the filing frequency for income statement and balance sheet data was changed from quarterly to semiannually for medium regional carriers with annual operating revenues under $10 million. Semiannual financial data for these carriers appear as a supplement in June and December issues of this publication. Classification of carriers within groupings is reviewed annually. When a carrier's frequency of filing financial data is changed because of reclassification, it may be necessary to use prior publications to obtain historical data. Data include income statement and balance sheet figures, in separate sections, by carrier entity for the most recent quarter and twelve-month period, and similar data for like periods in the previous year.
Air Carrier Industry Scheduled Service Traffic Statistics (Blue Book) incorporates the scheduled service activities of the Part 298 Small Certificated and Commuter Air Carriers with Large Certificate Medium Regionals into one group in one volume. It includes group totals for Large Certificated Air Carrier groupings. The data are obtained from the carrier reports on either Form 41, Schedule T-1(a) or Form 298-C, Schedules A-1 and T-1. Only Scheduled Service statistics are presented, since the Part 298 exemption authority air carriers report only their Scheduled Service traffic. Only system Scheduled Service totals are presented for each carrier, since the Form 298-C, Schedule A-1, does not give a domestic and international breakout. Data consist of passenger and cargo capacities and traffic actually carried in Scheduled Service for Medium Regional carriers (including Commuters), and summary tables for all carrier groups for the most recent quarter and twelve-month period, and similar data for like periods in previous years.
Air Carrier Traffic Statistics (Green Book) contains monthly airline operating statistics for more than 100 large certificated air carriers, based on data reported to DOT by carriers holding a certificate issued under Section 401 of the Federal Aviation Act of 1958 (now codified in the U.S. Code) which operate aircraft designed for maximum seating capacity of more than 60 seats or a maximum payload capacity of more than 18,000 pounds, or which conduct international operations. The data consist of passenger and cargo capacities and traffic actually carried, by carrier geographic entity (such as Domestic, Latin America, Atlantic and Pacific) and class of service in both Scheduled and Nonscheduled (or charter) Service for the most recent month and twelve-month period, and similar data for like periods in the previous year. Data are summarized by carrier entity (D, L, A and P) and carrier group (major, national, etc.)
Airport Activity Statistics of Certificated Route Air Carriers, 199x (where x is the current year, with about a year delay; for instance, calendar year 1996 data were published in 1997) contains the volume of revenue passengers, freight and mail traffic handled by the nation's Large Certificated Air Carriers at each airport service during the 12-months ending December 31, of the year of the report. In addition, a presentation of aircraft departures is shown including detail by Aircraft Type for total departures performed in Scheduled, Nonscheduled and All-Services. The data are compiled from information reported to DOT by the Large Certificated Air Carriers. These carriers hold Certificates of Public Convenience and Necessity (CPN) issued by the DOT authorizing the performance of air transportation. Large Certificated Air Carriers operate aircraft with seating capacity of more than 60 seats or a maximum payload capacity of more than 18,000 pounds or conduct international operations. Data for Commuters, intra-state, nonscheduled air taxi operators, and foreign flag air carriers are not included in this publication.

Airline Service Quality Performance (ASQP) Reports of 14 CFR Part 234 (On-Time) Data
Carriers with one percent or more of total domestic scheduled service passenger revenues are required to report data for their flights involving any airport in the 48 contiguous states that account for one percent or more of domestic scheduled service passenger enplanements. The regulation also provides for the voluntary reporting of a carrier's entire domestic system and voluntary reporting by other carriers. The reporting carriers have uniformly elected to report their total domestic system operations. Some of the data elements included are: departure, arrival and elapsed flight times as shown by the Office Airline Guide (OAG), the carrier's computer reservations system (CRS), the carrier's actual performance; selected differences among the three sources, such as delay and elapsed time difference; and the causes of delays.
