Trying to check in and getting error message "ssci-message.message.1011.title ssci-message.message.1011.description" on a 3-segment flight (YOW-YUL, YUL-LHR, LHR-OSL), 24 h before first segment. Called AC and was told that the problem was the international segment, and that I needed to try 24 h before the international segment. (That has never been an issue before, but ok.) Tried that, and still no luck. Any ideas?
