Useful booklet looking at Airmail services during World War II. Highlights the routes flown by locally registered Empire carriers within British Asia and those foreign countries that provided services to, from or through the region. It shows how routes were established, amended and abandoned as the ebb and flow of war dictated. A brief summary of the routes flown by B.O.A.C. is provided, followed by details of the services offered by the locally registered companies. This is followed by the services of the foreign countries that operated to or through British Asia. Each country then has a summary of the services available to it, with the final section devoted to notes on the postal history and special services available.
