For the modern postal historian, a "jusqu-a" cover is not just a piece of paper; it is a glimpse into a time when mail traveled by air as far as it could—and then sailed the rest of the way.
Jusqu'à Airmail Markings: A Definitive Study of Ian McQueen’s Philatelic Legacy
Because many of these stamps were applied in haste, clear, fully legible strikes of the jusqu'à text are much more valuable than faint or partial inkings. Conclusion
World War II radically altered global flight paths. The occupation of Europe and the dangers of Mediterranean airspace meant that traditional air routes were severed overnight. McQueen’s study details how until-airmail markings were used adaptively during the war to guide mail through circuitous alternative paths, such as the famous "Horseshoe Route" via Africa and India.

Many major postal hubs created specific rubber or metal handstamps. These often featured a box or a frame containing the words "Jusqu'à..." with a blank line where the clerk could write the destination city. Others included the city name directly within the stamp matrix if a specific route was heavily used (e.g., "JUSQU'A LONDON").
The usage of Jusqu'a markings spans a specific, clearly defined historical window. McQueen’s study heavily focuses on the period starting around —the immediate aftermath of World War I, when commercial aviation began taking off—up until the mid-1950s .
However, planes frequently flew only to regional hubs or continental coastlines. If a passenger or postal patron in London addressed a letter to a remote village in the interior of Australia, an airplane might only carry that letter jusqu'à (as far as) Karachi or Singapore.

He documented the various types of "Jusqu’à" handstamps used globally.
While many philatelists have touched upon these markings, the definitive, seminal work on the subject remains the research compiled by expert philatelist Ian McQueen. His specialized study dismantled the complexities of these markings, providing a structured framework that collectors still use today to authenticate and understand transit mail. Understanding the "Jusqu'à" Concept
Collectors categorize these markings based on how they were applied to the cover: The occupation of Europe and the dangers of
To appreciate the significance of McQueen’s study, one must first understand the terminology. The phrase Jusqu'à translates from French as "as far as" or "up to."
Upon its publication, the study was hailed as “a ground‑breaking study on this previously neglected field of aerophilately”. It was, in the words of one reviewer, “the first book I am aware of that shows all known air mail markings from various countries, to indicate that a letter was to be carried part way or to a particular point by air”. By bringing together scattered information from numerous sources and presenting it in a coherent, country‑by‑country format, McQueen effectively created a new sub‑specialty within aerophilately.
