The United Kingdom travel market hit a record £56.6 billion in gross bookings in 2025.
Demand is strong, digital adoption leads Europe at 90% online penetration and every major segment is growing. By most measures, this is a healthy market firing on all cylinders.
So why does the distribution picture look like a stalemate?
Phocuswright's newly published U.K. Travel Market Essentials 2026 shows a market where the numbers are moving, but the channel dynamics largely are not.
Online travel agency (OTA) gross bookings reached £10.3 billion in 2025, a record in absolute terms. But OTA share of the online market has declined for three consecutive years, from 22% in 2023 to 20% in 2025 and is projected to fall further to 19% by 2029. Meanwhile, supplier-direct share, despite years of aggressive investment in owned digital channels, moved only three percentage points over the entire six-year forecast period, from 78% to 81%.
Neither side is breaking out. The market has essentially decided who gets what territory, and the boundaries are hardening.
Three players control the overwhelming majority of U.K. OTA gross bookings: Booking Holdings at 44%, Trainline at 23% and Expedia Group at 16%.
That level of concentration hasn't produced momentum.
OTA year-over-year growth collapsed from 27% in 2023 to 3% in 2025 and is projected to stay in low single digits through 2029. British Airways has committed £750 million to IT infrastructure and £100 million specifically to artificial intelligence (AI) and data analytics. Tour operators account for nearly 40% of total U.K. gross bookings and have pushed supplier-direct online revenue to 80% of their segment.
The direct investment is real and sustained. The share gains, relative to the scale of that investment, are modest.
The one segment where the contest remains genuinely open is hotels.
In 2025, supplier-direct online and OTA channels held near-equal positions in U.K. hotel distribution, at roughly 35% and 32%, respectively. OTA hotel share is expected to decline only slightly to 31% by 2029. Hotels remain the last live battleground, and that balance is not expected to shift dramatically in either direction.
One wild card could yet redraw the map.
Great British Railways, the incoming state-integrated body set to begin operations in 2027, is expected to centralize fare management and ticketing across the U.K. rail network. Trainline's 23% share of U.K. OTA gross bookings depends on an open distribution model that GBR has the structural authority to reshape. How that plays out may be the most consequential distribution story in the U.K. market over the next three years.
