Auditing travel rebooking approvals in an executive office

Key takeaways

• Separate the schedule choice from the cost approval.
• Record the policy reference and any exception approver.
• Report approvals granted after ticketing as a distinct exception.

Question and scope

This audit asks whether an executive office can measure the completeness of a CEO travel rebooking approval. The unit is one rebooking event attached to one traveler and one itinerary. The review examines the original itinerary, the reason for the change, the options presented, the approval, the policy reference, the traveler confirmation, and the final cost. It does not evaluate whether the trip was necessary or whether the fare was the lowest available.

Set the scope to one executive office and a fixed period. Record the travel policy, the approval thresholds, the booking system, and the roles allowed to authorize a change. If the policy or the travel provider changes during the window, separate the periods. A new threshold can change the approval pattern more than a change in individual practice.

What the sources establish

The GAO Green Book describes internal control principles for authorization, documentation, and monitoring. NIST privacy guidance is relevant to limiting the traveler information retained in the audit file. The U.S. Small Business Administration offers general guidance on business controls and records. None of these sources defines a rebooking approval standard or supplies a local cost benchmark. A current policy page should be checked before the next quarter begins.

The office therefore needs local evidence for its own process. Public sources can explain why authorization and a policy reference matter, but they cannot show whether a specific rebooking was approved within the right boundary. The study should define the evidence standard and preserve the decision trail. A local count is more useful than a general claim that travel is controlled.

Definitions and measures

Define a rebooking event as a change to a confirmed itinerary that affects the date, time, route, carrier, or fare. Define approval as the documented decision by a person with the authority to accept the change and its cost. Define a policy exception as a change that exceeds a threshold or requires a higher-level approval. Define traveler confirmation as the traveler's documented acceptance of the new itinerary.

Measure the number of rebooking events, the number with a stated reason, the number with options and costs, the number with an approval, the number with a policy reference, and the number with traveler confirmation. Report the number of exceptions and the number of approvals granted after ticketing. A low exception count without the approval evidence can hide an uncontrolled process.

Sampling and collection

Sample rebooking events rather than itineraries, then review every message, approval, and receipt attached to the selected event. Include changes initiated by the traveler, the executive, and the travel provider. Stratify by cost band and by whether the change was same-day. Record the sampling rule and the observation window. If the office has few rebookings, extend the window rather than combining cost bands.

Collect the original itinerary, the change request, the options, the approval, the policy reference, the ticket receipt, and the traveler confirmation. Mask traveler identifiers in the analysis table. If an approval was verbal, record who gave it and when. A verbal approval that the policy does not allow is a finding, not an exclusion.

Analysis and reporting

Report the number of events, the number with an approval, the number within policy, the number with an exception approval, and the number with traveler confirmation. Show the counts by cost band and by initiator. Report the time between the request and the approval. A fast rebooking that bypassed the policy reference is not a complete control. Report the number of rebookings with no policy reference as a separate count.

Inspect the exceptions. Was the policy threshold unclear, was the approver unavailable, or did the traveler accept a cost without a record? Group the causes and choose one change, such as a required cost field or a same-day approval path. Do not rank assistants by the number of exceptions when the travel mix differs.

Limits and sources of error

The audit cannot prove that the fare was reasonable or that the trip was necessary. It can show whether the approval and the policy reference were documented. A travel provider may also change a schedule without the office's request. Report that event separately rather than counting it as an approval failure. Record the provider-initiated change as a separate category in the report.

The approval may have occurred in a phone call that was not logged, and the traveler may have confirmed verbally. The reviewer should record those gaps as limitations. A rebooking within policy is still a finding, not proof that the process is perfect. Consistent definitions matter more than a large sample.

Review and next action

Choose one change: require a cost field, add a policy-reference field, require traveler confirmation, or create a same-day approval path. Assign the owner and the next sample date. Repeat the audit with the same definitions and the same cost bands. Keep the change small enough to test for one quarter. Write the change into the travel request form so the next trip follows it.

Close the audit when the office accepts the result and schedules the next check. Report the remaining uncertainty beside the approval counts. The [travel rebooking routine](/blog/keeping-a-ceos-travel-rebooking-inside-the-approval-boundary/) describes the process this audit measures. Use the result to improve the record, not to judge the traveler.
