The structural picture of private aviation has shifted in the last twelve months. Three changes are now permanent, and a serious concierge desk has to plan around them in writing.
1. Sustainable aviation fuel mandates
European departures now carry a mandated minimum percentage of sustainable aviation fuel (SAF). The mandate scales upward every year through 2030. The practical implication is that SAF supply is now a scheduling constraint, not a back-office cost item. Major FBOs at LBG, GVA, FCO and TLS hold SAF inventory; secondary FBOs may not. A flight plan from a secondary FBO at peak season can be rejected at the slot stage if SAF inventory has not been pre-confirmed.
We pre-confirm SAF availability at the departing and refuelling FBOs before the slot request goes in.
2. FBO capacity at peak European airports
Le Bourget, Geneva and Nice are slot-controlled even for private aviation in July and August. The slot regime is administered by the relevant airport authority and by the FBO operator. Slots open at fixed times before the calendar week — typically T-7 days — and close within minutes. Walk-up requests are no longer entertained at peak.
We hold standing relationships with slot coordinators at the major French and Swiss FBOs. A summer departure from LBG by a regular client is requested as part of an annual block, not as a one-off.
3. Russian airspace
Russian airspace remains closed to European-registered private aircraft. Routes that previously transited via the polar corridor (Europe ↔ Northeast Asia) now route via the Middle East or via the Aleutians, adding two to three hours of flight time and one or two technical stops.
We have re-built our standard route packages for Paris/London ↔ Tokyo/Seoul to account for this. The standard fuel stops are Doha or Dubai southbound and Ted Stevens / Anchorage northbound. The technical stop FBOs are vetted and pre-cleared for our regular clients.
What this means for short-notice flights
A "two-hour notice" departure was always a marketing phrase. In 2026 it is meaningful only when:
- The departure FBO has confirmed SAF inventory for the aircraft's tank
- The slot at the destination is either uncontrolled or pre-held by the operator
- The route does not require permits from authorities with multi-day lead times
- The aircraft is positioned at the right FBO
For our regular clients, all four conditions are quietly maintained as standing infrastructure. We talk to the FBOs once a quarter. We hold pre-approved overflight permits for the corridors our principals use. The two-hour notice is a real thing because the work was done in advance.
What this does not mean
It does not mean we can move heaven and earth at any moment for a first-time client. Standing relationships take twelve to eighteen months to mature. A new mandate's first flight is usually planned with a longer lead time than the eventual norm.
We are honest about this in the discovery conversation. A short-notice promise without the underlying infrastructure is the kind of promise that gets a concierge desk into trouble.
