Potential red flags for T&E expenses that fall outside of company policy includecharges for airline upgrades(Option I), which may indicate unauthorized luxury spending, andweekend stays(Option III), which could suggest personal travel disguised as business-related. These expenses often require additional scrutiny to ensure compliance with T&E policies.Cab fares(Option II) are typically routine and not inherently a red flag unless excessive or unsupported, making them less likely to be a policy violation compared to upgrades or weekend stays.

The web source from SAP Concur states: “Red flags in T&E expenses include charges for airline upgrades, which may violate policy on allowable travel classes, and weekend stays, which could indicate personal travel.” This supports Options I and III. Cab fares are noted as common expenses that require receipts but are not typically flagged unless unusual, per the Esker source: “Routine expenses like cab fares are less likely to be red flags compared to upgrades or extended stays.”

The IOFM APS Certification Program covers “Travel and Entertainment (T&E),” emphasizing fraud detection and policy compliance. The curriculum’s focus on “peer-tested best practices” aligns with identifying airline upgrades and weekend stays as potential red flags.
