SYD to EZE via AKL EZE-BOG via LIM and return. Arrived at Sydney airport at 7am for a morning departure to be told flight will be delayed until afternoon. Provided with a lunch voucher I spent the day at Sydney airport flight finally departed at around 1730. Arriving late to EZE I had missed my prebooked hotel shuttle and complained at the airline counter and they gave me a voucher for a hire car to my hotel which was nice. A340 was old seats were well worn and frayed overhead reading lights didn't work overhead baggage lockers difficult to close ancient entertainment system with flickering screen. Food was passable but nothing special cabin crew looked old and tired and mostly stayed in the galley chatting amongst themselves and were not very attentive. The pillow was so small and flat it was a waste of time as was the small think blanket. Every other flight I had within South America with this airline was very late causing inconvenience and disruption to my travel plans. My return flight to Australia was cancelled and I was driven to a hotel and picked up by bus the next morning only to face more delays uncertainty and poor communication from airline staff. This airline is a joke listen to me and many other people here when we say pay the extra money and fly to South America with LAN or Qantas but avoid Aerolineas Argentinas like the plague.
