Howe fought strongly against the extension plans for a second runway at Paya Lebar Airport, and advocated the building of a new international airport in Changi. This was despite the Cabinet's decision for the go-ahead in 1972, based on a British expert's report that it would cost less to expand Paya Lebar Airport and that there was not enough time to get Changi built up to meet increasing traffic needs. Howe gathered a team to reclaim land, widened and extended the old Royal Air Force airstrip to take Boeing 747s and build the terminal. In August 1981, operations stopped overnight at Paya Lebar Airport and restarted the next morning at Changi Airport. Howe's role in setting up Changi Airport won him credit in Lee Kuan Yew's memoirs.
