Corporate Travel Spend Is Rising 18% YoY - Here Is Where the Money Goes

Our platform processed just over 50,000 trips in the last twelve months across companies ranging from 80 employees to 2,400. When we ran the year-over-year numbers, spend was up 18.3%. That number gets cited a lot in headlines but rarely broken down in any useful way, so I want to do that here.

The short version: this isn't one big thing. It's five or six medium-sized things happening simultaneously, some of which are unavoidable and some of which are self-inflicted.

Air Is the Biggest Line Item, and It's Getting Messier

Average domestic airfare for business travelers in our data was up 14% versus the prior year. That's not the same as leisure fare increases — business travel tends to skew toward flexible tickets and last-minute bookings, both of which carry significant premiums.

The bigger issue we're seeing is booking lead time. The average business trip in our platform is booked 8.4 days before departure. The sweet spot for pricing is 14 to 21 days out. That 6-day gap is costing companies roughly $140 per round-trip ticket on average. Across a company doing 500 trips a year, that's $70,000 left on the table — not from bad luck, from process friction. Approval chains that take three days, budget holders who aren't available, travelers who wait until the last minute because past last-minute bookings got approved anyway.

Hotels: Rate Inflation Plus Category Creep

Hotel costs are up 9% in our data, which is slightly below national averages for business travel. The companies doing better than that number have negotiated corporate rates in their top 10 destination cities. The ones doing worse have employees self-selecting properties without guardrails.

Category creep is the real story here. In 2024, about 22% of hotel bookings in our platform were at properties classified as "upper upscale" or above. In 2025 that rose to 31%. Policy documents generally say "reasonably priced business hotel" — which apparently means something different to every traveler. When the policy doesn't name specific approved properties or set a rate cap, that interpretation gap compounds across hundreds of bookings.

Ground Transport: The Category Nobody Manages

Ground transport is typically treated as a rounding error in travel budgets, but in our data it's averaging 11% of total trip cost, up from 8% two years ago. Rideshare prices have risen sharply in most major cities, and more importantly, they've become the default for any trip segment where an airport shuttle or rental used to be the standard choice.

One client with 340 employees found that ground transport spend had grown 34% year over year without anyone noticing because it was buried in the "other" expense category. Once they added a ground transport sub-code to their expense system, they could see it clearly. The next step was setting per-day ground limits for trips under 48 hours — and spend dropped 19% in that category within two quarters.

Meals and Incidentals: The Gap Between Policy and Reality

Most companies have per diem limits for meals. Most of those limits haven't been updated since 2021 or 2022. The U.S. General Services Administration adjusts federal per diem rates annually, but corporate policies often lag by years.

We're seeing a lot of finance teams stuck enforcing a $60 daily meal limit in cities where a reasonable business lunch runs $35 and dinner is $55 before gratuity. Employees submit over-limit receipts because the policy is unrealistic, finance flags them but ultimately approves most of them to avoid conflict, and no one ever updates the policy. The result is a compliance metric that looks bad but isn't actually being enforced.

Three companies in our platform have moved to a blended daily limit instead of meal-by-meal caps. They set the daily total at market-realistic levels, stopped categorizing meals granularly, and saw a 40% drop in exception requests while spending about the same total amount. Less administrative friction, same cost outcome.

Out-of-Policy Bookings Are Still a Significant Factor

Across our platform, 27% of all bookings have at least one policy exception. That's been stubbornly consistent over the past 18 months. The out-of-policy premium — meaning the difference between what was actually spent and what a compliant booking would have cost — averages $87 per trip. At scale that adds up fast.

The exception breakdown is roughly: 41% are due to timing (booking inside the 7-day window where in-policy options are limited), 29% are accommodation choices above the rate cap, 18% are class-of-service upgrades, and 12% are miscellaneous. The timing-driven exceptions are the most addressable — they're largely a function of approval process speed.

What This Means for Your Budget

If your travel spend is up 18% and you don't know specifically why, the answer is almost certainly some combination of the above. The good news is that the timing-driven exceptions, the ground transport category creep, and the booking lead time issue are all tractable problems. They require changes to process and tool configuration, not culture overhauls.

The companies in our platform that have held spend flat or grown less than 10% year over year share two characteristics: they have automated approval routing that resolves requests within 4 hours, and they have real-time spend dashboards that finance reviews weekly rather than monthly. That's it. No elaborate policy rewrites, no mandated hotels, no travel police. Just faster approvals and earlier visibility.
