According to Google, there should be a Fare Tracking option in Google Flights. I just can't find it. Was it removed or is there another website I can use (paid or free) to track flight prices? I do use ITA Matrix but I see no reporting feature.

My husband told me to stop looking at business class flights East Coast, USA to Asia for a trip 10 months away. But I tricked him. I upgraded us to Polaris on our LIS-IAD flight in June, so he'll say "Yes we really do need to travel in business class."
