Yes.
I must say that most of my flights are still on *A carriers, and I've found the AC inflight crews to have dramatically improved over the past 5 years. That said, the AC ground staff are the rudest and least helpful of any airline I fly, particularly in YYZ and especially at the priority check-in counters. Am flying a lot of UA this week and the inflight attitude leaves much to be desired. I've also had very good service on AF during the last year, which has prompted me to book more with them.
