What can a traveler do if they do not receive confirmation of their cancellation?

When a traveler does not receive confirmation of their cancellation, the appropriate action is to contact the Authorized Official (AO) for clarification. This ensures there is no uncertainty about the status of the cancellation. By reaching out to the AO, the traveler can obtain accurate information and verify whether the cancellation was processed successfully or if any further steps are needed.

Relying on assumptions about the cancellation being successful could lead to unwanted consequences, such as incurring costs for a trip that was not intended to be taken. Proceeding with the trip without confirmation could result in additional complications if the cancellation did not go through. Requesting a new authorization without clarity on the first cancellation would not address the underlying issue and could add further confusion to the situation. Thus, contacting the AO provides a direct and effective means of resolving the uncertainty surrounding the cancellation status.
