Documentation tips
- Only flights taken for legitimate business purposes (client meetings, conferences, training) are deductible — personal or vacation travel is not, even if booked through a company card.
- Keep boarding passes, itineraries, and a log of the business purpose for each trip; the IRS requires documentation of destination, dates, and business reason.
- If a trip combines business and personal travel, only the pro-rated business portion of the airfare is deductible; document the business days vs. personal days carefully.
- Delta's corporate travel program (Delta Business) can simplify expense reporting by centralizing billing and providing itemized statements — useful for audit support.
- Baggage fees, seat upgrade fees, and in-flight Wi-Fi charged separately are also deductible business travel expenses when the underlying trip is business-related.
