Philippines-based carrier Cebu Pacific is ordering another pair of Airbus A330-300s.
Airbus has confirmed the agreement, without giving details on delivery times.
The airline, which is stationed in Manila, already operates six of the type.
Cebu Pacific chief executive Lance Gokongwei says the aircraft has "proven to be the right choice" for its long-haul, low-fare services.
“The newly ordered aircraft will enable us to add more long haul routes, including the launch of our first flights to the USA."
No engine selection has been disclosed, but Cebu Pacific's current A330s are all fitted with Rolls-Royce Trent 700 powerplants.
Cebu Pacific had indicated in June that it was looking to take another two A330s, possibly for routes to Honolulu and the Middle East region.
