Business Travel Prices Set to Cool in 2027, but UK Buyers Shouldn't Bank On It

Global business travel airfares are forecast to rise just 1.5% in 2027 — a sharp slowdown from 4.7% growth this year — according to the GBTA 2027 Global Business Travel Forecast, produced with travel management company ALTOUR. Blended fares would reach $767 next year, up from $756 in 2026. For UK finance teams setting 2027 budgets this month, that sounds like relief. It's only partly true.

What does the forecast actually say?

The headline numbers are the friendliest in several years. Airfare growth slows across the board in 2027: 1.1% for economy, 2.2% for premium. Hotel average daily rates follow the same arc — up 3.7% in 2026 to $168, then a gentler 1.8% in 2027 to $171. Car rental rates rise 3.6% this year before stabilising.

Supply is doing some of the work. GBTA counts a record hotel construction pipeline of 15,922 projects, roughly 2.4 million rooms, helping keep rates in check. That's a real counterweight to pricing power — but note what the forecast describes as the cause of 2026's elevated prices: a fuel shock. Fuel shocks fade; structural cost pressures, as the UK is about to find out, don't.

The behavioural data deserves attention too. GBTA reports 2026 brought 7.2% spending growth against just 1.3% trip growth. Translation: companies paid roughly 6% more per trip to travel essentially the same amount. Any budget that tracks spending without tracking trips can hide how little travel the money actually buys.

Why can't UK buyers budget for under 2%?

Three reasons, and none of them appear in the global average.

First, Europe starts from a higher base. North America and EMEA are expected to post some of the strongest airfare increases in 2026, driven by capacity constraints, higher operating costs and delayed aircraft deliveries. The 2027 slowdown is real, but in Europe it begins from prices already outrun of budgets. If your 2026 spend ran behind actual prices, applying 1.5% on top compounds the shortfall.

Second, Heathrow gets more expensive. From 1 January 2027, the maximum per-passenger airport charge rises to £28.66, and airlines pass those charges through in fares. More significant is the regulator's long-term price control for Heathrow, due to be finalised in April 2027 — it will set charges for the years covering the airport's heavy expansion spending. Travel programmes routing through the UK's main hub should expect that cost embedded in fares for some time.

Third, premium is rising twice as fast as economy. A budget that applies one inflation figure across all cabins will underestimate senior staff and long-haul travel costs — precisely where premium cabins absorb a large share of spend.

In plain terms: the global 1.5% is a floor for UK buyers, not a planning number.

Where can companies claw back savings?

Slower rate growth shifts negotiating leverage from suppliers to buyers, and 2027 looks like a renegotiation year.

• Hotel programmes. With rate rises easing and 2.4 million pipeline rooms arriving, companies with predictable volumes in specific cities should use 2026 data to press for better corporate rates or added value — breakfast, flexible cancellation, free wifi. Even low-volume firms gain by consolidating stays with fewer hotel groups.
• Rail on short-haul. For Paris, Brussels and Amsterdam, rail often matches or beats flying on total journey time once transfers and security are counted — and it sidesteps airport charges entirely. Trainline's expanded partnership with Amex GBT is making European rail easier to book for corporate travellers, with emissions benefits on top.
• Advance booking windows. The early-versus-late booking gap runs wider for business travellers, who book at short notice. A policy target for advance booking, with emergency exceptions, cuts costs without cutting trips.
• Hub choice. Regional airports, alternative London airports and other European hubs can beat Heathrow on certain routes. Travel managers should compare rather than default.

What's the checklist for 2027 budgets?

Five steps cover most of it. Start from actual 2026 spending, not the 2026 budget — reset the baseline before applying any inflation figure. Use separate assumptions per cabin, weighted by each cabin's share of the programme. Build in a margin for Heathrow routes and revisit it after April's price-control decision. Renegotiate hotel rates now, before contracts renew. And track trips as well as spend — the 7.2%-versus-1.3% gap in 2026 is the warning.

The bottom line: this is the most encouraging forecast in years, but the relief won't be spread evenly, and UK buyers face Heathrow charges, a higher European base and premium inflation the headline conceals. With suppliers facing a softer market, this is the moment to negotiate — not to accept next year's rates.
