Top 3 of 38 tracked origin markets shown; relative demand is indexed to the #1 market = 100. Each market is gated by the UK's real entry requirements (visa or ETA) and direct-flight connectivity per origin market, as of the snapshot date above. Domestic demand is excluded — this corridor measures cross-border demand only.
Blind-market flag: Saudi Arabia registers modest English-language search volume in this corridor but is understated by design of English-only models — Arabic-language and non-Google search behavior means real demand is higher than search alone shows. KnowDemand flags these rather than silently under-ranking them.
Markets to deprioritize first: among reliably-measured markets, Kazakhstan, Taiwan, Ukraine (listed alphabetically) currently sit among the weakest gated demand in this corridor by Demand Index — typically weak measured interest or heavy gating by visa/ETA access and connectivity. Blind or understated markets are never listed here: understated is not the same as weak.

FAQ

London demand, answered.

Which countries fly to London the most?

United States, India and Canada lead cross-border route-search demand for this corridor across the 38 origin markets KnowDemand tracks (July 2026 snapshot) - roughly 87,000 monthly route searches from United States alone, with United States posting the corridor's highest calibrated Demand Index at 70. Each market is gated by the UK's real entry requirements (visa or ETA) and direct-flight connectivity per origin market. The full ranked corridor of all 38 origin markets is available in a pilot.

How is London flight demand gated?

Each origin market's raw route-search interest is gated by the UK's real entry requirements for that nationality (visa or ETA) and by direct-flight connectivity to London. High interest with low access converts poorly, so gated demand is what the ranking reflects.

What conversion should marketers expect from these origin markets?

Search interest converts at very different rates per origin market because access differs: the corridor is gated by the UK's real entry requirements (visa or ETA) and direct-flight connectivity per origin market, so a market's Demand Index already reflects how much of its raw interest can realistically convert. KnowDemand publishes each market's gated Demand Index alongside its relative demand precisely so budget follows convertible demand; per-market conversion detail is part of a pilot.

Is any origin market understated in this corridor?

Yes. Saudi Arabia (Arabic-language and non-Google search behavior) is a known blind market for this corridor: native-language, non-Google search behavior means English-language search models understate it, so KnowDemand flags it rather than silently under-ranking.
