The flight was smooth with minor turbulence. The staff was courteous. Since I have an aeroplan account I was able to use the inflight wifi. I wanted extra space and the window seat and I had to pay for that. At first, I was okay with that, however, I felt that it was the same distance between for everyone. Maybe I could be wrong.
