The flight attendants were very rude, unhelpful, and dismissive. One particular flight attendant was very unprofessional as she was talking rudely to other passengers and slamming/slinging our luggage around which was very uncalled for. Also, my 10 year old daughter started feeling nauseous during our 8 hour flight, and none of the attendants wanted to assist. They ordered me back to me seat as I got up to ask if they had Sprite (soda) to help with her nausea (the seat belt light was not on at the time). I've never had a bad flight experience such as this and we will not be flying Air-Canada again.
