HighworthcitizenguyHenley & Partners forecasts as many as 165,000 millionaire relocations in 2026 — the largest single-year movement of private wealth on record, up from 142,000 in 2025. That migration leaves a measurable trace in the sky. Global business jet departures reached a record 3.88 million in 2025, roughly 34% above pre-pandemic 2019 levels, and the busiest long-haul corridors now map closely onto the routes wealth itself is taking. For HNWIs assessing where to base, private aviation data has become an unusually honest indicator of which hubs are actually winning.

Key Takeaways
- Henley & Partners projects up to 165,000 millionaire relocations in 2026, following a record 142,000 in 2025.
- Business jet departures hit a record 3.88 million globally in 2025, around 34% above 2019, with fractional ownership activity up more than 75% over the same period.
- London–Dubai has entered the top ten global private jet corridors, and London–Geneva ranks among the busiest routes worldwide — both tracking UK wealth outflows.
- Roughly 7,000 additional millionaires are expected to relocate to Dubai in 2026, carrying an estimated USD 7 billion in capital.
- Air connectivity has shifted from a lifestyle consideration to a substantive criterion in HNWI residency decisions.
The Corridors That Show Where Wealth Is Moving
Private aviation traffic is a leading indicator because it precedes formal relocation. Families fly to inspect property, meet advisers and establish presence months or years before a tax residency is filed. The resulting route data therefore reflects intent rather than paperwork.
Two corridors illustrate the point. London–Dubai has climbed into the top ten busiest global private jet routes, a direct reflection of the UK wealth exodus following the abolition of the non-domiciled tax regime. London–Geneva, meanwhile, remains among the busiest routes worldwide, tracking the parallel flow of UK-based wealth toward Switzerland’s lump-sum taxation and banking infrastructure.
The destination data corroborates it. The UAE has been the leading destination for millionaire migration for two consecutive years, with net inflows approaching 10,000 in 2025. Forecasts point to more than 7,000 additional millionaires relocating to Dubai during 2026, bringing roughly USD 7 billion of investable capital with them. The Middle East and Africa region accounted for around 11% of global business jet market revenue in 2025 — approximately USD 5.3 billion — and continues to grow.
Why Connectivity Now Shapes Residency Decisions
For a family office with operating businesses in three jurisdictions, physical accessibility is a governance issue. Tax residency regimes increasingly rest on substance and day-count tests, and day-counting is materially easier from a hub with dense private and commercial connectivity.
This is where jurisdictions differentiate. Dubai combines a zero personal income tax regime with the infrastructure at Al Maktoum and Dubai World Central to absorb heavy business aviation volume. Geneva offers proximity to Swiss private banking and the Alpine second-home market, though slot constraints are a recurring frustration. Monaco has no airport of its own and depends on Nice, which in practice functions as a dedicated HNWI gateway. Malta and Cyprus have both positioned business aviation registries and maintenance capacity as part of their broader investment migration offering.
The structural point, as we examined in our analysis of why HNWIs keep choosing UAE tax residency, is that the fiscal case and the logistical case now reinforce one another. A jurisdiction with favourable tax treatment but poor connectivity imposes a hidden cost on families who must maintain presence elsewhere.
What This Means for HNWIs
Treat connectivity as a due-diligence line item. Before committing to a residency programme, map actual flight times to the family’s operating businesses, schools and advisers. A four-hour additional leg each way materially affects whether day-count thresholds are comfortable or fragile.
Read route data as a market signal. Sustained growth on a corridor typically precedes prime property demand in the destination. Corridor data is a useful cross-check on luxury real estate investment theses.
Assess aviation cost structure by jurisdiction. Import VAT on aircraft, registry requirements, crew visa treatment and hangarage costs vary widely and can exceed six figures annually.
Do not over-index on a single hub. Henley & Partners notes that regional instability in the Gulf has prompted a new phase of contingency planning among internationally mobile residents. Optionality across two jurisdictions is increasingly the default structure.
Country Comparison
United Arab Emirates. Strongest inbound millionaire flows globally, zero personal income tax, exceptional business aviation capacity. Principal considerations are regional geopolitical risk and rising cost of prime property.
Switzerland. Lump-sum taxation for qualifying foreign nationals, deep private banking infrastructure, and Geneva’s position as a primary European business aviation hub. Higher effective cost base and cantonal variation in treatment.
Monaco. No personal income tax for most residents and unmatched density of wealth, but severe property scarcity and full dependence on Nice for air access.
Cyprus and Malta. EU membership, competitive non-domiciled and residency frameworks, and improving aviation infrastructure. Connectivity is adequate rather than exceptional, which favours families whose primary operations are within Europe.
Risks and Considerations
Private aviation data is directional, not definitive: charter and fractional activity can reflect leisure demand rather than relocation intent, and a single corridor can be distorted by a handful of frequent operators. Migration forecasts are estimates built on partial datasets, and firms publishing them frequently have commercial interests in investment migration.
Operationally, aircraft ownership introduces its own residency complications — crew employment, permanent establishment questions and VAT exposure can all be affected by where an aircraft is based. Rising environmental taxation of private aviation across several European jurisdictions is a further cost variable that families should model over a ten-year horizon rather than a single year.
The Bottom Line
Private aviation flows are not a vanity metric. They are among the earliest observable signals of where internationally mobile wealth is relocating, and the current data points decisively toward the Gulf and Switzerland as the primary beneficiaries of the UK outflow. For HNWIs structuring a relocation, connectivity belongs alongside tax treatment and political stability in the decision framework — not after it.
