The "regional" two-class 772s won't get the spacebeds under this programme. [Those aircraft typically do SIN-KUL, SIN-HKG, SIN-NRT, SIN-BNE.]
However, the new 777-200ERs (J/Y only) which were launched on the temporarily suspended SIN-AMS-ORD will be re-fitted with Spacebeds. They will gradually replace the A340-300s on trans-con routes as more aircraft are delivered.
