Industrial troubles with the pilots delayed the start of services until 26 April 1924, when a daily London–Paris route was opened with a de Havilland DH.34. Thereafter the task of expanding the routes between England and the Continent began, with Southampton–Guernsey on 1 May 1924, London-Brussels–Cologne on 3 May, London–Amsterdam on 2 June 1924, and a summer service from London–Paris–Basel–Zürich on 17 June 1924. The first new airliner ordered by Imperial Airways, was the Handley Page W8f "City of Washington", delivered on 3 November 1924. In the first year of operation the company carried 11,395 passengers and 212,380 letters. In April 1925, the film "The Lost World" became the first film to be screened for passengers on a scheduled airliner flight when it was shown on the London-Paris route.
