Capacity to Jersey is being raised by 60,000 seats following the delivery of a larger aircraft to Channel Islands carrier Blue Islands.
The new 72-seat ATR-72, which entered service on Thursday, replaces a smaller 46-seat turboprop.
The addition means that the airline will now operate a fleet of five ATR-72s.
Blue Islands currently operates 900 flights a month, with its regional network expanded this summer to include new scheduled routes from Jersey to Norwich, Dublin and Rennes.
The airline runs scheduled services from Jersey to Southampton, Bristol, Birmingham, East Midlands and Exeter plus a Guernsey-Southampton route in addition to summer flying to Jersey for tour operators in Germany, Switzerland and The Netherlands.
Chief executive Rob Veron said: “Our fifth ATR-72 aircraft demonstrates Blue Islands’ commitment to providing year-round, sustainable connectivity and socio-economic benefits for the Island.
“It also underpins our positive but measured approach to growth as we emerge from the difficult market conditions caused by the pandemic over the past two years.”
He added: “As we grow our network, we are also very aware of the need to balance our wider environmental impact.
“Our ATR aircraft fleet is powered by efficient turboprop engines producing the lowest emissions per seat in its class. In addition, our partnership with Durrell’s Rewild Carbon programme, a world leading initiative run from Jersey, enables us by offsetting to make all of our flights carbon neutral and genuinely sustainable.”
