Philippine Airlines will upgrade the aircraft used on its Auckland-Manila route to a newer and bigger Airbus A330 aircraft.
Starting on June 17, the plane will replace the smaller A340 used on the non-stop route that operates three times a week.
The current four-engine A340 has 254 seats while the newer two-engine aircraft has 309 seats.
The shift increases the overall route capacity by 22 per cent, helping to stimulate leisure and business travel.
The links are worth an estimated $13.6 million a year to the New Zealand economy.
