What ef83 says. This year will be challenging due to heavy discounting this summer but they should be a strong set of results for this FY. The northern summer is when most airlines make their money (hopefully covering the winter loss and more) resulting in an annual profit.
I can imagine winter losses are extremely common for Euro airlines and even Ryanair have reported winter losses previously only to make a profit overall. Winter schedules contract significantly and aircraft are parked up for the season or for certain days of the week to reduce the losses.
They also have bags and bags of unrestricted cash. Many competitors just have vast amounts of debt.
