RAA: Commuter and Small Certificated Air Carrier Traffic and Capacity Statistics
This table summarizes the T-100 traffic data reported by Regional Airline Association (RAA) member carriers. The monthly summary is compiled by carrier entities (geographical regions in which a carrier operates), service classes, and domestic/international flights and includes available seat miles (ASMs), revenue passengers enplaned (PAX), revenue passenger miles (RPMs), revenue departures performed (FLIGHTS), and load factor. The summary includes reported international flights and military service which may not be available in the T100 segment and T100 market data tables released in TranStats. RAA member carriers, regardless of revenue, operate aircrafts with less than 100-seats and primarily on short to medium-range routes.
T1: U.S. Air Carrier Traffic And Capacity Summary by Service Class
This table summarizes the T-100 traffic data reported by U.S. air carriers. The monthly summary is compiled by carrier entities (geographical regions in which a carrier operates) and service classes, and includes available seat miles (ASMs), available ton miles (ATMs), revenue passengers enplaned (PAX), revenue passenger miles (RPMs), revenue ton miles (RTMs), revenue air hours (RAHs), revenue miles flown (MILES), and revenue departures performed (FLIGHTS). T1 summary includes reported international flights and military service which may not be available in the T100 segment and T100 market data tables released in TranStats.
T2: U.S. Air Carrier TRAFFIC And Capacity Statistics by Aircraft Type
This table summarizes the T-100 traffic data reported by U.S. air carriers. The quarterly summary is compiled by aircraft types/configurations, carrier entities (geographical regions in which a carrier operates), and service classes, and includes available seat miles (ASMs), available ton miles (ATMs), revenue passenger miles (RPMs), revenue ton miles (RTMs), revenue air hours (RAHs), revenue miles flown (MILES), revenue departures performed (FLIGHTS), and aircraft fuels issued in gallons. T2 summary includes reported international flights and military service which may not be available in the T100 segment and T100 market data tables released in TranStats. Note of Change: T-2 released after 7/13/2006 contains all service class summary data. See T-2 Change Details.
T3: U.S. Air Carrier Airport Activity Statistics
This table summarizes the T-100 traffic data reported by U.S. air carriers. The quarterly summary is compiled by origin airports, carrier entities (geographical regions in which a carrier operates), and service classes, and includes scheduled departures, departures performed, passengers, freight, and mail. T3 summary data is only compiled for carrier entities that report data for all three months within the quarter. For three years before and including the current year, the data only includes origin airports in the U.S. and is compiled by carrier with no carrier entity information.

   Terms and Definitions
Aircraft Days AssignedThe number of days that aircraft owned or acquired through rental or lease (but not inter-change) are in the possession of the reporting air carrier and are available for service on the reporting carrier's routes plus the number of days such aircraft are in service on routes of others under interchange agreements. Includes days in overhaul, or temporarily out of service due to schedulecancellations. Excludes days that newly acquired aircraft are on hand but not available or formally withdrawn from air transport service.
Airline IDAn identification number assigned by US DOT to identify a unique airline (carrier). A unique airline (carrier) is defined as one holding and reporting under the same DOT certificate regardless of its Code, Name, or holding company/corporation. Use this field for analysis across a range of years.
Airport CodeA three character alpha-numeric code issued by the U.S. Department of Transportation which is the official designation of the airport. The airport code is not always unique to a specific airport because airport codes can change or can be reused.
Airport IDAn identification number assigned by US DOT to identify a unique airport. Use this field for airport analysis across a range of years because an airport can change its airport code and airport codes can be reused.
Carrier CodeCode assigned by IATA and commonly used to identify a carrier. As the same code may have been assigned to different carriers over time, the code is not always unique.
City Market IDAn identification number assigned by US DOT to identify a city market. Use this field to consolidate airports serving the same city market.
Express FreightProperty, other than passenger baggage transported by air, with a premium paid over standard freight charges for more rapid delivery.
Non-Revenue TrafficPassengers and cargo transported by air for which no renumeration or token service charges are received by the air carrier. Airline employees, officers and directors, or other persons, except for ministers of religon, who are traveling under reduced rate transportation authorized by 49 U.S.C. 41511(a) and 14CFR part 223, as well as travel agents, cargo agents, and tour conductors traveling at reduced fares are also considered nonrevenue traffic.
Passenger MileOne passenger transported one statute mile. Total passenger miles are computed by summation of the products of the aircraft miles flown on each inter-airport flight stage multiplied by the number of passengers carried on that flight stage.
RevenuePertaining to activities for which remuneration is received by the carrier.
Seat MileThe aircraft miles flown in each inter-airport segment multiplied by the number of seats available on that segment for revenue passenger use.
Ton MileOne ton (2,000 pounds) transported one statue mile. Ton-miles are computed by multiplying the aircraft miles flown on each inter-airport segment by the number of tons carried on that segment.
Unique CarrierUnique Carrier Code. It is the Carrier Code most recently used by a carrier. A numeric suffix is used to distinguish duplicate codes, for example, PA, PA (1), PA (2). Use this field to perform analysis of data reported by one and only one carrier.
Unique Carrier EntityUnique Carrier Entity. This field distinguishes entities used by two or more carriers with a numeric suffix, for example, 06038 and 06038 (1).
Unique Carrier NameUnique Carrier Name. It is the name most recently used by a carrier. If two or more carriers have the same most recent name, a numeric suffix is used to distinguish them, for example, Air Caribbean, Air Caribbean (1).
World Area Code (WAC)Numeric codes used to identify geopolitical areas such as countries, states (U.S.), provinces (Canada), and territories or possessions of certain countries. The codes are used within the various data banks maintained by the Office of Airline Information (OAI) and are created by OAI.
