That doesn't capture the range of their dark patterns. I am literally testing this now. I am on Delta website going through the booking process (redirected form Google Flights). The price at Google Flights was $578. Delta website is showing that 1 seat is available (at this price). When it prompts to select the seat there are no seats available at this price. I am offered to upgrade to Comfort+ for $60. I am already 10 min into the process. And just to preempt your possible argument: when I go to the previous page it still shows that 1 seat is available at this price.
