Alderney States will pay £120k to provide an extra 150 flights to Guernsey and Southampton next year.
States owned airline Auringy is currently working out its 2017 schedule with the government.
One hundred extra services to Southampton are being planned, with 50 extra return flights for Guernsey.
The £120,000 will come out of a £500,000 budget for transport initiatives.
The island's Economic Development Officer says they've made the move because of 'unsatisfied demand' and believes it will help 'economic activity'.
The spring/summer schedule is due to go online in the next few days.
