This is according to a survey conducted by World Travel Market, which discovered that 45 per cent of people polled will be discouraged from flying because of the rise in APD, which will take effect on Monday (November 1st).
A further eight per cent expressed concern that the increase would price them out of taking an overseas holiday altogether.
Fiona Jeffery, World Travel Market's chairman, said the rise is "a real concern to the travel and tourism industry".
"APD was doubled in 2007 and is now double the 2007 figure leading to the cost of flying abroad increasing," she explained.
"The World Travel Market surveys show both holidaymakers and the industry are significantly concerned by both next week's increase in APD and the proposed switch to a Per Plane Tax."
World Travel Market will host its opening ceremony in London on November 8th, when Boeing will discuss its 787 Dreamliner with members of the international travel and tourism industry.
