Cutting business travel costs is not about travelling less. It is about paying the right price for every trip that matters. The most profitable levers are nearly always the same: enforcing the travel policy at the moment of booking, booking earlier and controlling hotel spend. Next come rail, a single booking channel, service fees and expense reports.
Below are 8 levers ranked from highest to lowest impact, each backed by a sourced figure, followed by a worked example using Fairjungle's public pricing.
These figures come from different studies with different scopes, so they do not add up. They show the order of magnitude of each lever.
A travel policy sitting in a PDF saves nothing. According to a GBTA study, travellers who book outside policy spend an average of $2,881 more per year than those who follow it. They book luxury hotels and first-class tickets three times as often (TravelMole).
The answer is not more rules but rules shown where the decision is made: in the booking tool, with approval triggered only when a booking falls outside policy. To build those rules (caps, travel classes, approval flows, exceptions), read our corporate travel policy guide.
Airfares depend heavily on when you buy. According to 2025 ticketing data from ARC (Airlines Reporting Corporation), booking a domestic flight 1 to 3 months ahead saves 25% compared with last-minute bookers (Expedia press release). The same report shows that booking very far ahead is not always cheaper.
In practice: set a recommended booking window in the policy (for example 14 days for flights) and ask for a reason on late bookings rather than banning them.
Hotels are often where overspend builds up first. Fairjungle booking data shows most business hotel nights in Europe outside France cost between €120 and €180, with prices more than doubling from one city to another. City and seasonal detail is in our analysis of business hotel prices in Europe.
Two actions follow:
In France, rail is often the cheapest option in total cost: no airport transfer, no baggage fees and time to work on board. It is also the lowest-carbon option: a TGV emits on average 4 g CO2e per passenger-km, against 260 g for a short-haul flight (SNCF Connect, based on ADEME's Base Carbone).
Regulation points the same way: since a decree of 22 May 2023, domestic flights are banned on routes where the train takes less than 2h30. A simple rule for your policy: rail by default under a set journey time, air on justification.
You cannot cut what you cannot see. According to a 2026 GBTA study of 269 travel buyers in North America and Europe, an average of 32% of hotel bookings are made outside the company's managed channel (TravelDailyNews). Those bookings escape caps, negotiated rates and reporting.
Bringing flights, trains, hotels and cars into one tool gives a full view of spend. It is also what lets you negotiate with suppliers on real volumes.
Intermediation fees weigh less than ticket prices, but they are easy to reduce. One travel management company CEO puts agency fees at 2 to 4% of the total travel budget (TourMaG)..
Compare the billing model (per transaction, percentage, subscription) with your real volume. The worked example below shows how.
Expense reports are expensive to process. According to the GBTA Foundation, each one costs an average of $58 and 20 minutes; 19% contain an error, and fixing it adds $52 and 18 minutes (GBTA). The study dates from 2015 but remains the most cited benchmark.
The best way to cut that cost is to have fewer expense reports: when flights, trains and hotels are booked and invoiced directly to the company, travellers no longer pay them upfront. Only on-site expenses remain.
Cutting all travel is not a strategy: according to GBTA's 2025 Business Travel Index, 86% of business travellers rate their trips as worthwhile (GBTA). The lever is to sort trips: a client meeting or a team offsite justifies travel, an internal status meeting rarely does.
One simple question before approval often does the job: "Could this trip happen on video without losing value?"
Assumptions: a company with 40 active travellers per month and a travel budget of €400,000 per year. Calculated with Fairjungle's public pricing as of 30/10/2026.
The right plan depends on spend per traveller. At €15 per active user against 3% per booking, break-even sits at €500 of spend per traveller per month (15 ÷ 0.03). Above that, the per-user plan is cheaper. Below it, for occasional travel for instance, the percentage plan fits better.
Enforce the travel policy at the moment of booking. That is where travel class, hotel price and booking window are decided. A GBTA study puts the extra cost of an out-of-policy traveller at $2,881 per year.
For a domestic flight, 1 to 3 months ahead gives the best average prices, up to 25% cheaper than last-minute according to Expedia and ARC.
An average of $58 and 20 minutes according to the GBTA Foundation, plus $52 when it contains an error, which happens 19% of the time.
For short trips in France, rail is generally cheaper in total cost and emits about 65 times less CO2e per km than a short-haul flight. A "rail by default under a set journey time" rule is easy to apply.
Between 2 and 4% of the total travel budget, according to a TMC CEO interviewed by TourMaG. Compare that benchmark with your tool's billing model and your real volume.
Not always. Negotiated rates are on average 22.7% below public rates according to CWT Solutions Group, but in some markets they are higher. Negotiate where you have volume, and always compare with the public rate.
The biggest savings come from decisions made at booking: policy compliance, booking ahead, hotel choice and mode of transport. Service fees and expense reports complete the picture. A tool that applies the policy automatically and centralises bookings acts on all these levers at once.
