Anyone know if today's AC7991 is due to a delay of an inbound flight? It now shows leaving Toronto at 10:20, arriving at 12:53; which is great, since I can now get 7994 at 115 at 115pm, instead of 7996 at 455pm!

What's the chance that they would move up the flight time when they've published a delay? I've rebooked on to 7994, but if it were to move up I might have issues...
