ITA Matrix/Google Flights
I was wondering since Google bought ITA Matrix, is the Google Flights website now just ITA Matrix? Reason I ask, my wife was booking a flight to Denmark and had a great flight on American Airlines for a particular date. But then her work decided to change the week she needed to be there, and when we researched the next week, Google Flights did not show the same flight that was exactly a week before. Like there was no such flight anymore. But then she went to American Airlines website and searched for the new dates, and lo and behold, that same flight shows up there. ITA Matrix used to be the best way to search all airlines for flights, has Google changed it such that now it is awful and diverts to hide good flights?
Thanks
