>but this one was a small annoyance in my trip this month There are others. Unfortunately (for the airlines I use at least) there's no way for Google Now to know that a re-booked flight is not a new flight. I routinely need to change flight dates/times several times, but still get Google Now notifications for the original flights. I've had mild panic attacks on several occasions when I saw the "you need to have left for the airport two hours ago to get to your flight on time" popup.
