Thai Airways International joins the Dreamliner club in Auckland tomorrow, with its new Boeing 787-9 flying in from Bangkok.
The airline is also stepping up to daily flights from five times a week, adding about 65,000 seats to the route.
Thai's aircraft has 298 seats - 30 in business class in a 1-2-1 configuration and 268 in economy arranged 3-3-3. The new aircraft replaces a 777-200ER on the route.
Scott Tasker, Auckland Airport's general manager aeronautical commercial, has said the announcement was great news for New Zealand and would inject $53 million annually into the New Zealand economy.
"Thailand is a popular holiday destination for Kiwis, with more than 46,000 New Zealanders travelling there during the past year, with the majority of travellers being holiday makers."
