Merchant category codes (MCCs) that range from 3000 to 3308 are reserved exclusively for airlines.
Merchants under this category operate air travel businesses, perform maintenance at airports, and deliver freight via aircraft. Unlike in other MCC ranges, each MCC in the “Airlines” category is typically assigned to an individual merchant, rather than a group of merchants based around a common product.
Examples of specific MCCs in this range include:
| MCC | Description |
| 3000 | United Airlines |
| 3008 | Lufthansa |
| 3058 | Delta |
| 3066 | Southwest Airlines |
| 3082 | Korean Airlines |
| 3136 | Qatar Airways |
MCCs in this range are generally considered to be at a higher risk for chargebacks than other verticals. Customers might make a booking, then have a change of plans and use a chargeback as a way to recoup their funds, for example.
