Reporting its first-quarter results, the London-listed company upgraded its post-tax profit guidance for 2016 to between 175 million euros and 185 million euros from a range of 165 million euros to 175 million euros given in May.

The company said the upgrade came despite lower fuel prices feeding through into lower ticket prices in the market, a trend it said it expects to continue for the foreseeable future.
