Jersey-based Blue Islands ceased operations on Friday (14 November) and has cancelled all flights, just 11 days after Eastern Airways entered administration.
Blue Islands operated scheduled services, while Eastern flew charters to the Channel Islands.
Premier Holidays said it was in negotiations with carriers. “We anticipate all 2026 routes to be protected by end of the week,” it said.
Director Mark Godfrey added: “Premier Holidays has long valued its partnerships with Eastern Airways and Blue Islands, who have contributed positively to travel to and from the Channel Islands.
"However, our programme has never been solely reliant on any single carrier. We work with a broad range of airline partners, which has enabled us to move quickly and effectively to protect the vast majority of routes.
"Thanks to close collaboration with Visit Jersey and the States of Jersey, we have already secured alternative capacity and maintained continuity of travel for our customers.”
Premier said Loganair and Aurigny had added extra services. “As Channel Islands specialists, we’re working quickly to rebook travellers on a rolling 14-day basis, starting with those closest to departure, to arrange alternative travel.”
The operator said 2026 packages remained on sale and its operations team was contacting impacted customers in departure-date order to arrange rebooking. “At this point, we have been in contact with all customers up to December,” it said.
Premier added the situation highlighted the benefit of booking a package with an operator. "When unexpected issues arise, our agents and customers are never left to manage the disruption alone."
Just Go! Holidays said a small number of its passengers were affected, although none were departing until summer 2026. It added: “Alternative flights are being arranged for those guests impacted and the rest of their trip remains unaffected.”
Blue Islands had been due to operate flights for Newmarket Holidays' Jersey tour next year. Hayley Morris, Newmarket head of trade sales and partnerships, said: "We’re very sorry to hear of the collapse of Blue Islands. Although we had been using the airline for our ‘Jersey – The Sun-Kissed Channel Isle’ tour, our next departure isn’t until April 2026.
"Our team is already reviewing all existing bookings and will be in touch with affected customers to offer suitable alternative flight options."
Meanwhile, Loganair has launched "rescue" flights to Jersey from Exeter, Bristol and Southampton.
It initially stepped in with plans for a Southampton-Guernsey service but was forced to withdraw it from sale after only a few hours as, unlike other services, this route is designated as “essential” in government terms and a licence is needed.
Sasha Kazantseva-Miller, president of Guernsey's committee for economic development, told The Jersey Evening Post: "We designate some air routes as essential so that it allows us to have direct involvement in who operates it, and therefore the standard of service on that route.
"We have contacted Loganair to clarify that a licence is needed to operate the route and it does not currently have one."
Another issue that has arisen is Blue Islands had planned to start flying between Gatwick and Newquay later this month, replacing the link lost when Eastern Airways collapsed.
