DIRECT-SELL airline EasyJet has placed deposits with Boeing for twelve new 737 aircraft for delivery over the next two years, tripling the size of its present fleet. The airline, the first UK operator to bypass travel agencies by selling direct to the public, also plans to open three new routes by the end of 1997 - Jersey, Geneva and Oslo - with Belfast and Madrid also on the stocks. EasyJet founder Stelios Haji-Ioannou is under no illusion about his standing with the travel trade: 'We hate the travel agents and they hate us', he told an aerospace conference in Paris.
