Today, I was sitting inside my car staring at the Delta section of YVR. It took me a while to notice that the CX flight (HKG-YVR-JFK) parked in gate D73 was a B747-400 from its normal A340-300/600. I was waiting again for a while when I heard CX 838 approaching Vancouver. When it landed, it was yet another B747-400. This is rare; I have seen many A340's of CX parked at YVR when they used to make their technical stop on its way to YYZ but never before have I seen two B744 parked at the same time.
A JAL 744 was in the gate that CX 838 was supposed to use and again, I guess he had trouble understanding the ATC's orders to push back far enough to let the CX come into the gate. He waited a few minutes in D71 until the ATC instructed him to push back far enough to let the Cathay bird come into the gate.
It was a strange day today but does anyone know the reason that CX brought two of its B744 into YVR today? Is it just that the loads were high today or cargo?
