We’ve all gotten emails from American Airlines saying “ are you still looking at that trip to Miami?” or a note on the United app saying “hey, you should complete your purchase to IAD that you looked at three weeks ago”. So we know they track our searches.
Several times I have clicked through Google flights to the airline website and found a price and trip combo that I couldn’t get by searching the website by itself. So, if I’m going to track flight prices, I’m going to do it on Google Flights.
There are always people doing the same search as you
One reason for the fare change (e.g. increase) is likely decreased inventory. Closer to departure, it might be due to advance purchase expiration, which removes certain discounted fares even when inventory still exists.
You doing the same search 100 times without purchasing the fare has no bearing on the price, all other things remain constant.
