Low cost airline easyJet said on Tuesday it expected tighter security arrangements at UK airports to affect demand.

Probably that will have an impact at the margin on people's willingness to fly. The UK government needs to make some decisions quickly, Chief Executive Andrew Harrison told a conference in London.

Harrison also said easyJet had no plans to fly long haul routes. It was also in talks with suppliers on a possible introduction of in flight mobile phone services but was not close to a deal.

EasyJet said on September 7 it still expected to post a 40 to 50 percent increase in full year pretax profit despite disruption from tighter airport security.
