When do you use the 1801-C?

• A. To file each leg after the initial leg of a STOPOVER flight
• B. To file the initial leg of a STOPOVER flight
• C. For domestic flights only
• D. In place of the 1801

Answer: (A)

In a STOPOVER flight, you break the trip into legs: the first leg is filed one way, and any additional legs you plan to fly are documented on a separate form. The 1801-C is the form used to file each leg after the initial leg. This lets you update or add subsequent segments of your trip as you plan or as conditions change, without rewriting the entire plan. It’s specifically for those follow‑on legs in a stopover, not for the initial leg. It isn’t limited to domestic flights, and it isn’t a replacement for the initial 1801 form.
