Carolyn McCall, Chief Executive of easyJet, said, "EasyJet's solid financial performance in a tough trading environment demonstrates that the business model is strong. I'd like to thank the whole team at easyJet for their commitment and hard work over what has been a very tough year in the airline industry.
"I've now been at easyJet for four months and completed my review of the business and capital structure. The strategy will build on the strength of easyJet's network and target leisure and business customers with its best value fares to convenient airports. easyJet is strongly positioned to take advantage of the continuing profitable growth opportunities in European short-haul. This combined with margin improvement through a tight focus on costs and accessing new revenue opportunities, means that easyJet is poised to continue the strong operating cash generation of the past few years."
By 09:35 shares in easyJet were down 2.75 per cent on the FTSE 250 to 459.10 pence per share.
