Blue Islands has partnered wtih Scottish airline Loganair providing new air links with Aberdeen, Inverness and the Isle of Man.
Loganair is the UK's biggest regional operator following the collapse of Flybe in March.
The agreement means Blue Islands passengers will be able to book connecting journeys to any of Loganair's destinations via airports where both airlines have hubs, like Southampton and Manchester.
Loganair customers will also now see Jersey and Guernsey as potential destinations when booking through its website.
Blue Islands’ Chief Executive Rob Veron said the partnership further enhances Blue Islands' commitment to deliver robust and reliable regional air connectivity.
'We are excited to form this new partnership with Loganair, hand in hand with a significant expansion of our own route network after 15 years of Channel Islands’ centred operations.
'We are delighted to be able to offer customers an extended route network with the peace of mind of guaranteed connections, Air Passenger Duty savings and the easy convenience of checked-through hold luggage in a single ticket.
'Whether flying for business, leisure or visiting friends and family, this partnership once again boosts regional connectivity for the communities we serve in the Channel Islands and the UK using our Manchester and Southampton hubs to connect to destinations on the Loganair route network. Furthermore, it will provide vital support for our visitor economies, particularly in the Channel Islands as we can welcome Loganair customers from Scotland and the north east onto our services to Guernsey and Jersey.'
