Bear with me, this is my first trip report! I'm gradually moving from being a frequent Y flyer to an occasional J flyer, so I would be particularly grateful for any feedback as to what I did not/could do to make my own experience better, and how to make the trip report more useful for others.

Flight/Origin-Destination: AC 889 LHR-YOW, equip: 767-300
Date: 22 MAY
Cabin: J
Status: N/A

Pre departure
Was check in quick and efficient? Yes, but I was perplexed that I used the priority lane to enter the counter area then was in a 30-pax line to actually get my BP scanned and into the gate seating area.
Did you use priority security (if eligible) and if so, was it quick and efficient? N/A
Did you use the Maple Leaf lounge and if so, any feedback in regards to service, food and drinks? I found the London Lounge to be crowded and a little dirty. Too many people clamoring over the food. Washroom facilities were small. Question: would I have been able to use the T3 AC Arrivals Lounge instead? (I arrived on a BD codeshare at T1). I guess I should have used the BD arrivals lounge at T1 but frankly couldn't find it!
Was priority boarding offered (if applicable to your status) and efficient? N/A, arrived at gate while boarding underway
If there was a delay, did the gate agent provide timely updates? N/A

Onboard - J cabin:
Were the crew professional & well groomed? Yes. Looked like I had a rookie FA, he was really trying hard, and doing a great job, but as a self-professed "not a big drinker" he needed instructions on how to make a rye and ginger (which I prefer to him winging it, and led to my favourite question -- 'is this enough rye'?)
If there was a delay, were you provided with timely updates? Yes and no. 15 mins after scheduled departure we were informed (still at gate) that we had lost our departure slot (I suspect due to a minor medical issue as they had asked for a doctor on board a few minutes earlier). We pushed back 25 mins after that, were informed that we were 7th for departure, and rotation was another 30 mins later. Total delay 1hr, two announcements.
Was the IFE activated on the ground? Yes, due to delay.
Was a pre-departure beverage offered on the ground? Yes
Did crew offer to hang your jacket? No. I noticed a number of folks stuffing their jackets into the overheads.
Were newspapers & menus distributed and meal orders taken (Please specify when meal orders were taken - on the ground or in the air)? Yes. Meal orders taken on the ground.
Did crew offer a hot towel prior to the meal service? Yes
Approximately how long after take off did it take for the first meal service to be completed? (From takeoff to all items collected) 1.5 hours.
How was the quality of all the meals? Salmon appetizer was excellent. Chicken main with ratatouille and wild rice was decent.
Did the cabin crew continiously top up the beverage of your choice throughout the flight? Yes

Post departure
If you have checked baggage, did it arrive within reasonable period of time? No. 3 pcs tagged priority but pretty much the last off the plane. Waited 30 mins.

Overall experience/any other comments
It was an expensive ticket so three issues that would otherwise be forgivable were:
- discomfort in the lounge
- no priority line to get BP scanned and board
- luggage delay
