The airline and operator on Thursday (24 November) recorded a post-tax profit of £356 million for the six months to 30 September 2022, up from a £163.5 million loss during the same period last year.
Group operating profit, meanwhile, rebounded from a £170.4 million loss a year ago to a £516.6 million profit, despite "significant delay and compensation costs" running to more than £50 million.
Jet2 chair Philip Meeson pinned these costs on "the lack of planning and preparedness of many airports and associated suppliers". "Our operations were directly impacted by the broader disruption seen across the aviation sector and its supply chains in mid-summer," said Jet2.
