Parent company Dart said on Monday its profit for the twelve months ending March 31, 2018, would be boosted by "a more normalised pricing environment" for flights and holidays following a previous period of heavy discounting.

Its shares were up 14 percent to 740 pence at 0950 GMT.

Jet2.com, which last summer was Britain's fourth largest airline by passenger numbers and also sells holidays, would have benefited from the collapse of rival travel firm Monarch last year.

Monarch's demise came partly as a result of tough competition in the Spain, where a price war among airlines and tour operators coincided with hotels raising prices.

Monarch's collapse removed capacity from the market, easing pressure on prices, which has also recently boosted Jet2.com's bigger rivals easyJet and Thomas Cook.

Analysts had expected Dart to post pretax profit of around 95 million pounds ($133 million) this financial year, before raising those estimates to about 113 million pounds on Monday.

Dart, however, said it was cautious on pricing for the coming summer holiday period and it expected its performance for its next financial year to be in line with the current one.

Dart also runs a food distribution business in the United Kingdom, which it said was focused on growing its revenue pipeline.
