I am a very frugal traveler when it comes to choosing my destination. I use Google Flights and Skyscanner leaving the destination open to find cheap destinations I'm interested in visiting.

I'm signed up with all the airlines email alerts and several of them have the "discount code" you must enter in the search to get the low price. Does google flights account for these discounts? Am I wasting my time using the airline website? Could I see the same fare price by just using Google Flights and Skyscanner?
