i have an intra-european flight tomorrow morning on lufthansa then onwards to canada, also on LH. then a domestic flight on AC.

the LH check-in web page sends me to the AC check-in page which then tells me that check in opens 24 hours before the flight. immediately to the left of that message is text telling me that my flight is in 15 hours.

i assume that AC is only taking the domestic flight into account. as i will be asleep here at that time, i won't be able to check-in online beforehand. not a huge deal but i usually like to check-in online when it opens.

i'm just curious, though. does AC not see that the flights begin with LH? Where is the problem and is there any way to work around it?

[edit to add:] this is an AC ticket (014)
