Delta Airlines uses the "Misdirection" dark pattern to force customers to upgrade from the Basic to the Main Cabin package. They do this by prominently displaying a frictionless primary button that adds $26 to the bill with one click.
To avoid this additional cost, customers must actively search for and select the "Accept Restriction" checkbox and then press the less visible "Continue with Basic" link-style button. This design choice is intended to manipulate customers into making an impulsive purchase and is not a respectful approach.
This modal design uses a "Misdirection" dark pattern as it creates a sense of friction that pressures the user to take an action that results in a lower payment, while the biggest and most prominently displayed button on the screen, with just one click, leads to an additional charge on the user's card.
