Just go to show AC's equipment is quite old and is becoming increasing unreliable. I wonder how much longer can AC "keep postponing" - I mean real action rather than air balls, press releases with no true follow through such as the refurbrishment of some of their elderly jets like the B767's and first delivery A340's. The A330's are also beginning to show their age. AC announced with great fanfare last October about equipment updating. Five months later, we are still awaiting definitive announcement of product details and implementation scheduling.
