After many tries, all of a sudden, ONE of the two files allowed for OLCI....but the second one still did not. However, was able to get the Res Agent to assign the seats (this was on a Tango fare with 24hr advance seating at OLCI), and couldn't care less about notifying for checked baggage in advance...this was for domestic travel ex YYC, 1 pax for YVR and onwards to MEX, the other for YYZ onwards to YUL.
