Ok, I'm new to this program. I feel like a lot of times when I look for space, nothing shows up. I head over to United and see flights available. I've been playing around with different destinations and airlines and have found some. I realized the United shows itineraries with two airlines. I now know to ignore those on LifeMiles. But I can;t seem to get Copa routes to show up or Air Cananda down to GRU. For instance there is YUL-GRU on March 4 2019 save space on United, but nothing on Lifemiles.

Does LifeMiles always have such a discrepancy with save space on United Star alliance partners? FYI, I also see the same AC 96 on Aeroplan.
