Excludes days that newly acquired aircraft are on hand but not available or formally withdrawn from air transport service. |

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. |
| Carrier Code | Code 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. |

| Seat Mile | The aircraft miles flown in each inter-airport segment multiplied by the number of seats available on that segment for revenue passenger use. |
| Ton Mile | One 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 Carrier | Unique 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 Entity | Unique Carrier Entity. This field distinguishes entities used by two or more carriers with a numeric suffix, for example, 06038 and 06038 (1). |
| Unique Carrier Name | Unique 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). |
