Impressed that #GoogleNow alerted of cancelled flight tomorrow OSL-HEL on SAS. Phoned FlightCentre back home, who said automatic rebooking BRU-OSL / OSL-ARN / ARN-HEL. My agent said SAS first said couldn’t rebook, as originally issued as Air Canada flight, then eventually got override code. Now scheduled to fly BRU-ARN / ARN-HEL on a loose connection, arriving a few minutes earlier than originally planned. GoogleNow intelligently picked up flight cancellation from the booking on my Google Calendar.
