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 .
McQueen cataloged hundreds of unique handstamps, manuscript markings, and labels used by international postal administrations.
McQueen intentionally focused on handstamps that explicitly indicated a restricted air service, along with airmail cancels that marked the end of the flown portion. Not every routing marking qualifies.
Airmail markings, including Jusqu'a markings, are highly prized by collectors and researchers due to their historical significance and relative rarity. These markings provide a tangible link to the development of air transportation and communication systems, and offer a unique insight into the challenges and innovations of the early 20th century. By studying these markings, researchers like Ian McQueen can gain a deeper understanding of the evolution of airmail service, the growth of international air transportation, and the social and economic factors that drove these developments.
McQueen’s study highlights several distinct types of markings that aerophilatelists encounter. These markings can be broadly divided into three structural categories: Jusqu-a Airmail Markings- A Study Ian McQueen
McQueen provides an exhaustive listing of known "Jusqu’à" markings from across the globe, categorizing them by country, city, and specific physical characteristics. Historical Context: Beyond a mere list, the study explains the Universal Postal Union (UPU)
In the 1930s and 1940s, air routes were limited, expensive and often unreliable. A letter might be flown from London to Brindisi in Italy, but then be transferred to a ship for the crossing to Egypt or beyond. The sender could pay a reduced rate for “air as far as Brindisi, then surface”, and the postal administration would apply a Jusqu’à marking to show that the airmail etiquette had been honoured only as far as the agreed point. As Ian McQueen himself wrote, “These are the cachets that were employed to show how a letter could be sent by air only ‘as far as’ a certain terminal point for the airmail, where it would be transferred to a surface routing, and where it would often have an air cancel marking applied”.
: Usually applied when an airmail etiquette (blue label) or stamp was present, but the air service could not be completed for the entire route.
“The Jusqu’à marking is not merely a postal curiosity but a key to understanding the transitional phase from surface to all-air transport. Each marking tells a story of negotiated rates, national rivalries, and the gradual shrinking of the world.” The usage of Jusqu'a markings spans a specific,

: Does the marking align with known air service suspensions, line interruptions, or historical events (such as route changes during World War II)?
Ian McQueen’s Jusqu'à Airmail Markings: A Study (1993) and its 1995 supplement are considered essential reference works for aerophilatelists, documenting "partially flown" mail covers. The study acts as a comprehensive guide to worldwide "Jusqu'à" markings, which indicate the point at which mail transferred from air to surface transport.

The study provides an inventory of known handstamps organized by country of origin, where most of these marks were applied.
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").
By continuing to study and analyze jusqu'a airmail markings, researchers can gain a deeper understanding of the complex and intriguing world of philately and airmail history.
