How can see Google Now flights cards on my LG G2? How can see flights cards on my LG G2? I have Google Search, Google Now Launcher and G+ as well. I was looking at this article on how to activate flight search,  but I don't see these settings on my G2. 

Can anyone help?
If you've already activated the Fligth's card, then you only have to do a simple search on google. 
You WON'T have a card that let's you search for flights. Instead you'll have a card that remembers you of all the flights you searched. 
For example: if I search a flight with Emirates that goes from Milan to Dubai, then Google Now will keep track of all the flight's info. After I make the search and close the browser, in Google Now there'll be a card that tells me if there are delays, the airport of departure and the airport of arrival and all the other info.
Long story short: there ISN'T a Flights SEARCH card in Google Now; there is a Flights Card and that's different ;)

P.S.: if my answer helped you could you accept it? :)
