Avi-Go does not publish June empty-leg corridor volumes. This briefing uses the verified empty-rate and continental-retention facts — plus dense route structure — as an adjacency map for empty-leg desks.

This Limitless Sky thematic report (“Empty Leg Adjacency — Retention & Empty Rates”) is an editorial synthesis for charter desks, programme managers and researchers. Figures are drawn exclusively from the Avi-Go report windows listed in the methodology. Published 28 July 2026. Reading time estimate: 14 min read.

Blurb for distribution: Europe ~40% empty sectors vs NA ~30%, continental retention NA 99% / EU 90.45% / APAC 93.20% — adjacency map from verified facts. Tags: empty-legs, retention, adjacency, europe, north-america. The companion HTML page at /insights/reports/empty-leg-adjacency-retention mirrors this inventory for web readers using Josefin Sans and Lato under the Reserve visual language.

Executive summary

~40% — EU empty sectors (Jan–Aug 2025). ~30% — NA empty sectors (Same window). 99% — NA retention (Intra-continental). 90.45% — EU retention (Intra-continental).

The executive takeaway is structural, not promotional: Avi-Go shows where aircraft already fly; Limitless Sky connects that map to live empty-leg search and quote workflows. Readers should leave this summary with (a) the correct period label, (b) the primary hubs or cabins in scope, and (c) an explicit refusal to invent rates.

For Limitless Sky desks, “Empty Leg Adjacency” is usable as a routing and capacity map: identify the hubs and cabins Avi-Go already shows as dense, then confirm live availability on empty-leg boards and operator holds. Movement share is not a price. Rank order is not an AggregateRating. When MoM and YoY disagree in sign, quote both baselines rather than picking the friendlier print.

1. What is verified — and what is not

Empty-sector rates exist for Europe vs North America; June corridor empty volumes do not. This section of “Empty Leg Adjacency — Retention & Empty Rates” is constrained to verified Avi-Go fact keys only. Limitless Sky publishes the statements as Class B intelligence: citeable, period-labelled, and never converted into invented charter hourly rates. Readers searching private jet charter services, empty legs or hub concentration should use these pages to narrow geography and cabin class before requesting a live quote.

For Limitless Sky desks, “What is verified — and what is not” is usable as a routing and capacity map: identify the hubs and cabins Avi-Go already shows as dense, then confirm live availability on empty-leg boards and operator holds. Movement share is not a price. Rank order is not an AggregateRating. When MoM and YoY disagree in sign, quote both baselines rather than picking the friendlier print.

Verified statement (What is verified — and what is not). Business jets in Europe flew empty on approximately 40% of sectors Jan–Aug 2025 — versus ~30% in North America. Copy this wording into client memos with the Avi-Go period intact — paraphrasing away the month or the baseline is how desks accidentally invent a different market.

Operational reading: treat the figure as a structural prior for aircraft, airport or corridor shortlists. High density raises the probability of a match after peak banks; it never guarantees the exact cabin, date or empty-leg price a passenger wants.

Verified statement (What is verified — and what is not). North America retained 99.0% of business jet departures within the continent Jan–Aug 2025 — the most insular major aviation market globally. Copy this wording into client memos with the Avi-Go period intact — paraphrasing away the month or the baseline is how desks accidentally invent a different market.

Commercial reading: programme gravity and hub concentration can coexist with a long charter tail. Avi-Go operator and airport shares explain where inventory is likely to cluster — diligence on AOC, insurance and crew duty still happens outside this table.

Checkpoint after 2 statements in “What is verified — and what is not”: confirm the Avi-Go period still matches the travel window you are briefing. If you are comparing against another thematic report in this series, keep the source-report labels side by side rather than merging tables.

Verified statement (What is verified — and what is not). 90.45% of European business jet departures remained within Europe Jan–Aug 2025 — intercontinental share just 9.55%. Copy this wording into client memos with the Avi-Go period intact — paraphrasing away the month or the baseline is how desks accidentally invent a different market.

Verified statement (What is verified — and what is not). Asia Pacific retained 93.20% of departures as intra-continental flights Jan–Aug 2025 — second-most insular region after North America (99.00%). Copy this wording into client memos with the Avi-Go period intact — paraphrasing away the month or the baseline is how desks accidentally invent a different market.

Checkpoint after 4 statements in “What is verified — and what is not”: confirm the Avi-Go period still matches the travel window you are briefing. If you are comparing against another thematic report in this series, keep the source-report labels side by side rather than merging tables.

Note — Limitless Sky will not invent June empty-leg rates by corridor.

Note — Use live empty-leg boards for price and availability; use Avi-Go for structural probability.

Section close — “What is verified — and what is not”: any follow-on commercial decision still requires a live aircraft hold, passenger count, dates and cabin preference. Market structure from Avi-Go narrows the search space; it does not replace operator confirmation. Limitless Sky’s empty-leg feed and quote desk remain the transactional layer.

2. Why Europe creates more empty adjacency

Higher empty-sector rates plus multi-country short-haul lattices raise repositioning frequency. This section of “Empty Leg Adjacency — Retention & Empty Rates” is constrained to verified Avi-Go fact keys only.

3. Dense corridors where matches are most likely

High Avi-Go density raises match probability after peak banks — it never guarantees the cabin you want. This section of “Empty Leg Adjacency — Retention & Empty Rates” is constrained to verified Avi-Go fact keys only. Limitless Sky publishes the statements as Class B intelligence: citeable, period-labelled, and never converted into invented charter hourly rates. Readers searching private jet charter services, empty legs or hub concentration should use these pages to narrow geography and cabin class before requesting a live quote.

4. North America’s opposite problem

Extreme continental retention means most empty adjacency stays inside NA rather than leaking intercontinentally. This section of “Empty Leg Adjacency — Retention & Empty Rates” is constrained to verified Avi-Go fact keys only. Limitless Sky publishes the statements as Class B intelligence: citeable, period-labelled, and never converted into invented charter hourly rates. Readers searching private jet charter services, empty legs or hub concentration should use these pages to narrow geography and cabin class before requesting a live quote.

Methodology & citation discipline

All quantitative claims in this Limitless Sky thematic report resolve to verified Avi-Go fact statements already inventory-linked in the Limitless Sky knowledge slice (entity_facts / insight fact dictionaries). No charter prices, AggregateRatings or unverified model-of-the-month crowns are invented.

Period labels are mandatory. June 2026 monthly analytics are not interchangeable with Avi-Go RD200 full-year 2025 figures or Jan–Aug 2025 regional analytics, even when the same airport, operator or aircraft model appears in multiple cuts. MoM baselines use the prior calendar month; YoY baselines use the same month in the prior year when labelled.

Empty-leg adjacency sections use verified empty-sector rates and continental retention where available. June corridor-level empty volumes are not present in the Avi-Go cut and are therefore not fabricated. Live empty-leg boards remain the source of truth for price and availability.

Where two Avi-Go cuts disagree in level but agree in rank order, Limitless Sky trusts rank order for routing intuition and the labelled period for any numeric citation in client memos. That habit prevents quoting a June monthly airport total as if it were an annual figure.

How to brief this report to a client

1) Open with the hero stats and the primary Avi-Go window. 2) Walk the hub or corridor map relevant to the itinerary. 3) Separate MoM seasonality from YoY trend. 4) Offer two alternate airports when Avi-Go flags a concentrated hub. 5) Request a live quote — never invent a rate from a movement table.

Programme buyers should also separate fractional / jet-card products from on-demand charter. Operator shares hint at programme gravity; contract quality still depends on AOC, insurance, cabin configuration and crew limits.
