Went from Toronto to Vancouver and back within 24 hours. Both flights in J both departing within 1/2 hour of each other. Here is a mini trip report... On the outbound flight the crew seemed bound and determined to do as little as possible. Offered initial drink and nuts, no nuts refill. Salad served with no attempt to top up drinks even though my glass of wine was almost empty. Main course served and by the time they came around with wine I had already finished my meal. A little while later cookies and ice cream were passed around and then it was lights out - time to let the passengers on this afternoon flight have a nap so that they wouldn't bother the crew. The usual assortment of unhealthy snacks were offered about an hour before landing. On the return trip I had some of the best service I've ever experienced in AC J. The food/drink service was as it should be. the Service Director consistently addressed everybody by name, took the time to chat with passenger and build rapport - she seemed to genuinely love her job. She and her crew mate were constantly in the cabin offering people refills of water, wine, whatever. Thanked me and another million miler for our business, acknowledging that it is thanks to passengers that she has a job. My outbound was on a 763 - which I'd been looking forward to due to the pod and my return was a 321 - worst J in the non-RJ fleet, but the service made the 321 flight seem so much nicer. Consistently inconsistent. sigh.
