The latest national airfare figures look almost flat after inflation, but they do not give a business travel manager a ready-made budget. The Bureau of Transportation Statistics reported on September 25 that the average domestic fare in the second quarter was $436.36.
That was 0.02% below the first quarter’s inflation-adjusted $436.45. In unadjusted dollars, however, BTS said fares rose 2.0% from the first quarter. The two comparisons answer different questions: purchasing power changed very little, while the nominal amount increased.
Know what the average includes
The BTS release measures itinerary fares, including round trips and one-way tickets where no return was purchased. It includes required charges and taxes at purchase, but excludes optional items such as baggage, upgrades and assigned-seat selection.
The figures use a 40% ticket sample under the OD40 programme. BTS moved from the earlier 10% sample beginning in July 2025, so readers comparing longer histories should pay attention to that change in the data collection.
This is a report about travel purchased for a past quarter. It is not a quote for an October client visit or a forecast that every route will become cheaper.
Build a trip budget around the actual journey
For an owner approving a trip, the useful comparison starts with the same route, dates and requirements. A fare that looks attractive on its own may involve different baggage allowances, departure times or flexibility. Record those conditions beside the price before comparing options.
A simple approval sheet can show the airfare, anticipated ground transport, accommodation and necessary extras separately. That makes it easier to understand why two trips with similar ticket prices have different total costs. It also gives the employee a clear explanation of what has been approved.
Include the purpose of the trip and the time the traveler needs to arrive. A low fare is not a saving if the itinerary cannot support the meeting. Conversely, paying more should have a stated reason, such as a schedule requirement, rather than an unexplained preference.
Compare your own experience consistently
Small businesses do not need a complex travel dashboard to learn from bookings. Start with a record of the route, booking date, travel date, ticket conditions and final expense. Over time, compare similar trips instead of averaging together very different journeys.
Keep changes and cancellations visible. An initial booking price and the amount ultimately paid can diverge. If the purpose is to improve budgeting, the final expense and the reason for any change are more informative than a screenshot of the cheapest fare seen during the search.
Our earlier report on NASA’s airport taxi tests explored the operational side of travel planning. The fare data add a separate financial perspective; neither removes the need to plan a realistic journey.
Use the BTS average as context when reviewing the travel budget, then test assumptions against the trips your business actually needs. The distinction between an inflation-adjusted trend and a cash expense is especially useful when explaining why a nearly unchanged headline does not necessarily mean a lower bill.
