Lower than expected winter losses will boost annual profits at Jet2.com and Jet2holidays parent company Dart Group.

In a trading update this morning, Dart said: “The group believes that pre-tax profitability for the year ended 31 March 2013 will be ahead of current market expectations.”

Overall forward booking levels for budget carrier Jet2.com for the year to March 2014 remain in line with its 13% increase in capacity for this summer.

“Jet2.com continues to be supported by the successful expansion of Jet2holidays and its sales of great value package holidays,” the company said.

“The group continues to develop and build its businesses, and we are cautiously optimistic about our ability to increase profits in the current financial year, notwithstanding the continuing tough economic environment.”
