Leisure travel company Dart Group (LON:DTG) said on Monday that it expects underlying profit before tax to be ‘materially’ ahead of previous expectations, sending shares up nearly 15 percent.

The group attributed the change in expectation to the ‘continued success of our growing Leisure Travel business and a more normalised pricing environment after the heavy discounting in the market over the past year’.

The group also said that forward bookings for summer 2018 were ‘satisfactory’ so far, adding that the performance of its two new operating bases at London Stansted and Birmingham airports was encouraging.

“It is still early in the leisure travel booking cycle and we remain cautious on pricing”, the group added.

“However, given the satisfactory forward bookings and the execution of our growth strategy, the Board currently expects the Group’s trading performance for the year ending 31 March 2019 to be broadly in line with the current financial year.”

Shares in Dart Group are currently trading up 14.55 percent at 744.00 (0858GMT).
