Cathay Pacific (CX) will launch a premium economy product on its Boeing 777-300ERs from March 2012. The aircraft will be in a 340-seater configuration and be dubbed a 77G in the GDS inventory.

The 777 will have 40 business class seats, 32 premium economy seats in a 2-4-2 layout and 268 economy seats in a 3-3-3 design. This layout contrasts with the two 777-300ER versions—77A and 77D—which have six first-class suites, and either 57 or 53 business-class beds and 238 economy seats.

CX would not confirm the change but simply said, “Our view is that premium economy is moving from being a niche product in certain areas to being a more general product.”
