What happens if you take AC91 EZE-GRU and then the next day take AC91 GRU-YYZ? I assume that shows up as separate flights but how do the systems even determine that? I guess in this case the departure date makes it obvious but in the reverse direction the departure dates aren't even the same for the same flight.
