Hi, I have a return ticket from AEP to BOG via GRU. I am flying from bogota to buenos aires in a week with TAM/LAN, and i got an email today saying my flight which was arriving at AEP at 13:00 has been cancelled, and they have booked me another flight and i arrive at EZE at 20:20 - same day. Because of this i will be sitting in GRU for around 12 hours, and instead of a 10 min taxi ride to my apartment it will be over an hour and cost me US$50 instead of US$5. In most western countries if your flight is delayed/cancelled and the delay is longer than 4 or 5 hours they have to give you food, hotel, cash etc compensation. I have checked TAMS website and it doesnt really say anything about compensation, rights etc - well except for fights from/to USA. The fight was booked in argentina via tam.com.br. Does anyone know what are my rights as i want to know before i rock up to the check-in/customer service desk - does anyone know what TAM/LAN usually do - TAM is a star alliance member ?
