I can only thank most of you but the issue is in at least Brazil, one cannot access AC Reservations or even Altitude/....I could b0k throgh another engine but I have a creidit I want to use on AC Medal. Here in Brazil I cannot even log into my Altitude account for e-upgrade purposes on my return flight. AC flys here from both YYZ and now YUL to GRU.
must state this is not the first time I have experienced this problem as I come to Brazil at least 2 or 3 times a year but this problem started about 3 or 5 years ago so it is on going without any action by AC.
