Schedules file customers are supplied with a standard carriers file that contains a column to indicate controlled IATA code duplicates. If an exclamation mark "!" is appended onto the IATA code, it means it is a controlled duplicate. We also recommend using an additional field, such as the carrier's name, to match accurately.
