On the other hand, UA's computer system for releasing international upgrades is pretty smart. If the J cabin is empty enough, it will release a whole bunch of upgrade and award inventory exactly 3 days before departure and it clears the waitlist by status. (That means the computer system will automatically review each flight when it reaches a particular # of hrs before departure which I doubt AC's computers are capable of.) If the flight is overbooked, it will also close out the upgrade inventory for op upgrades at the airport.
With AC, there is really no sure way of predicting C class on international flights which makes Aerolotto that much harder to win.
