Pros: The attention of the crew is very good. They are very friendly and, on the return trip there was attention of Argentine hostess. The meal options are very good as the vegetarian menu I previously requested. Fly NZ30 ON FEBRUARY 28 th
Cons: The seat I reserved paying additional dollars to have no one in front of me is bad. The table has little stability and the space that one acquires to stretch the legs is dangerously occupied by food carts that pass very close. The seats are tight. And the great kindness of the crew succumbs to the bad Argentine behavior of occupying the empty seats. On the flight back to Bs.As. many overweight people were overcrowded by the bad luck they had when buying their tickets, however, thin people, who did not pay for better places, were located in an empty seat where, usually, they go familiar with babies and traveled peacefully in a place that did NOT correspond. We all understand that the spaces are small but they should take better care of the passengers and, by common sense, if there are free seats, offer them to those who for physical reasons and their full rows are uncomfortable throughout the trip which, in itself, is very long . I suggest that you put options of Latin Spanish doblabas movies on the flights you make from Buenos Aires to Auckland. FLY NZ30 on February 28 th

Cons: The flight was delayed by 3 hours making me late for the next two flights and ultimately costing me an entire day longer in transit. While I understand these things happen, Air Canada's response to me asking for help was abysmal. Ultimately, they didn't care and told me it was my problem. Sadly, one of the first people I talked to really did want to help and arranged flights that would have gotten me back on track but he was prevented from confirming the changes due to management. I will never fly with Air Canada ever again.
