Portsmouth, Southsea and Isle of Wight Aviation
In ignorance of the Post Office monopoly the company issued labels for a 3d additional fee to the ordinary postage for the carriage of mail on their flights. Twenty covers were flown between Portsmouth and Ryde and a further twenty on the return flight. The covers were signed by the pilot, A.W. Whitta, and the Air Ferry Service labels cancelled by a cachet. The Post Office stopped the company flying any further air mail and the Island Air Express labels were not flown on covers. During 1935 the airline also carried copies of the Portsmouth Evening News to the Isle of Wight, copies of the paper bearing a bright green cachet showing an outline of an aeroplane and the words 'BY AIR' in white.
