Airline passengers are facing higher costs because of European Union plans to include international aviation in its emissions trading scheme, says Air New Zealand.
The airline said it was disappointed by the decision of the EU's Court of Justice to uphold plans to include international aviation in the scheme from next year.
"Similar to the recently increased UK departure tax, higher costs due to the EU [emissions trading scheme] will need to be passed on to passengers and will be advised in due course," the airline said.
The British Government is increasing air passenger duty in April from £85 to £92 ($172 to $186) per passenger coming to New Zealand.
Tourism Industry Association chief executive Tim Cossar had said the latest rise in departure tax meant a family of four would pay more than $736 in taxes just to leave the country and would price more potential visitors to New Zealand out of the market. United Continental Holdings, American Airlines and the Air Transport Association of America challenged the EU's attempt to extend the world's largest carbon cap-and-trade programme beyond its borders. The Luxembourg-based court's ruling, which can't be appealed, means the rules will be imposed on any flights to and from EU airports starting next year.
