Data point: I was missing a connecting flight on A3 (the AC transatlantic segment posted within 24 hrs) so had to wait 2 weeks to file through the online form. At first the system gave me the "this flight has posted" message so I had to upload proof of travel such as the ticket and boarding pass. Got the standard "we will be in touch in 6 to 8 weeks" message but the correct SQM/SQD showed up within minutes. So whatever AI interface they're using worked well as I'm sure it wasn't manual human intervention.
