Review of Air Canada flight Toronto → San Francisco in Business

My first transcon flight! And Air Canada made it a great pleasure. Previous flights from our journey:
Paris (CDG) - Toronto (YYZ) - here
Toronto (YYZ) - Santiago (SCL) - here
Santiago (SCL) - Toronto (YYZ) - here

Air Canada Transborder Lounge

I was surprised by this lounge a little bit. We arrived at 6:40 and it was quite full but we were able to find our seats with no problem in a quiet corner and got a nice but basic breakfast. The only hot option was and oatmeal made with water instead of a milk. Disgusting! But as I said for basic breakfast it was just enough.

There are available two showers, just as in the international lounge. I find this number very small but both were available in this early hour in the morning so we jumped on it and enjoyed.

AC737

Well, I got tired by saying that I consider Air Canada Dreamliners very nice and the product overall great. So if you would like more comments, please refer to previous posts.
On this flight, we got usual breakfast and the crew was again very nice and made our flight pleasant. I enjoyed the option of having dined on demand as we had our breakfast in the lounge and I wanted to sleep after take off which I did for at least one and half hour.

The only unpleasant experience we got was after landing at SFO, where we waited for 1 hour on the tarmac! Yes, one hour! Incompetent idiotic Ground handling at SFO was not able to deal with the airplanes arriving and departing so our journey from runway to gate was 1 hour. Disaster!
