Finnair has launched its Change for Good campaign this year in support of Unicef's initiative to bring clean water and a clean environment to the children of India.
Passengers on any of the carrier's flights will be given the opportunity to donate some of their leftover holiday money to the good cause.
Collection envelopes will be placed in seatback pockets and anyone is free to place money in them, which will then be collected at the end of the flight.
Christer Haglund, senior vice president at the airline, said: "Finnair and its customers have already collected nearly €1 million (£910,000) for Unicef work through the Change for Good campaign."
