I was booking a business class flight from CUR-MIA-DCA for early December which I was tracking on Google Flights. I checked and Google flights had the price at $621 so I went to aa.com to book it. When I searched for the same flights, the business class ticket came up as $871.89. This was not too surprising as Google probably doesn't update their prices as often as the airlines. For kicks, I went back to Google flights and clicked on the "Book with American" link which took me to aa.com where the price was $622.39! Both searches were for the same flights on the same day in the same cabin with the same number of passengers. Flights booked into I class and was ticketed at the lower price.

After booking the flight, the price on Google flights is now showing $867. Has anyone else seen instances of where the price going directly to aa.com was higher than can be achieved by going through a third party link to aa.com? I assume there was only 1 seat left in the I bucket, but then why didn't that price show when searching on aa.com?
