Flew to EZE on July 30th. Flight was full in both sections. J Class service was fine...a 767 with 1/2/2 config. 1 stop in Santiago where everyone must leave the plan for a crew change. When we re.boarded I was the only one in J class....On my return there were two of us from EZE to Santiago then off the plane again for a crew change. Then onto Toronto where the flight was full in both sections. Had seat 1A..single widow/aisle. I have heard that starting in November?? AC will go direct to EZE 3 days and then to Santiago and 3 days to Santiago first..theb EZE. Argentina was a great destination..Buenos Aires lots of fun!!!
