I'm a *A Elite/Gold on Air Canada and thinking of booking a YVR-PEK-SIN and HKG-PEK-YVR flight on CA. Looks like the planes will be A321, A330 and 767-300/300ER. Any experiences to share? IFE and power in each seat? Meals, in any? Will likely do it in Economy and I could only find J experinces posted.
