I flew business class from Toronto to Santo Domingo (Dominican Republic). Total travel time was about 6 hours and 40 minutes, which included a one-hour layover and change of planes at Miami International Airport. The Toronto to Miami portion was in an Airbus A319, and Miami to Santo Domingo in a Boeing 737MAX 8. I was happy with all the seating and service. The cabin crew members were friendly, attentive and helpful. I find business and first class great on American, but I find the economy class overall quality and service to be lacking. However, this was a business class trip, and everything was great.
