It’s been a turbulent time for the aviation industry recently. And now another airline looks unlikely to weather the storm. Flybe is up for sale, with the regional air carrier calling in accountants from KPMG in an attempt to save itself from collapse. Half-year profits have plunged and the company’s auditor, PwC, warned of “significant doubt” over its future. KPMG's involvement should have instantly set alarm bells ringing, as they were also the administrator of Monarch Airlines last year.
