Google Now - Flight Search

[damo]

Hi,
I'm having problems with Google Now. previously if I searched for a flight online, this would come up as a new 'card' and was very useful to me. Over the last couple of days, this has stopped and no longer appears as a 'card'
I'm using a Nexus 4 running JB 4.3

Hi Damo can you tell me more about Google Now?

What do you need to know?
