Flights from Alderney to Guernsey and Southampton will still be without a designated provider after the States of Guernsey rejected a set of bids.
The Economic Development Committee took responsibility for finding a company to operate the routes last year and they received four bids in December.
However they say none of the bidders have "convincingly demonstrated it is able to fully deliver sustainable PSO (Public Service Obligation) services to the required standard and in the required time frame."
It will mean that regular flights from Alderney to Guernsey and Southampton will remain uncertain.
The Committee has said it will now work on alternative requirements which will seek to attract bids that can meet the air connectivity needs of the island.
They have said they will be in close contact with the States of Alderney, as well as the Health and Social Care Committee, the Employment Committee and the States Trading Supervisory Board to create an alternative specification.
Back at the start of 2017 Guernsey's Policy and Resources Committee wrote to Economic Development Committee asking them to take responsibility in finding a new designated provider for Alderney's air routes.
An invitation to tender the routes was made in October last year, where it was established two distinct services were needed (one to Guernsey and one to Southampton) to operate year-round, several times a day.
The Economic Development Committee has said it will aim to share a new specification of requirements for the next set of bidders for the routes before the end of June.
