The airline already flies seasonally to the Island from Norwich, Humberside and Edinburgh and is due to launch the new routes – to Inverness and Aberdeen – in the coming months.
But it is not yet known how frequently the services will operate.
Jonathan Hinkles, chief executive of Loganair, said the company was saddened by the demise of Flybe but added that they had been prepared for it.
‘By stepping in quickly with a comprehensive plan, Loganair is aiming to maintain essential air connectivity within the UK regions to keep customers flying, and to offer new employment to former Flybe staff members who are facing an uncertain future today,’ he said.
‘The plan represents the outcome of several weeks of behind-the-scenes contingency planning work, during which we’ve evaluated many routes and aircraft.
‘It is critical to the continued success of our own airline that we refrain from over-expansion, and that our growth can be delivered within our operational and financial means.
‘I am confident the plans being announced today are robust and sustainable, enabling former Flybe customers to benefit from Loganair’s high standards of customer service and on-time performance on a range of new routes, with a strong emphasis on those to and from our Scottish heartlands.’
