I think that's still really stretching. "In fact, it's only the lowest price in that ticket class".
If I saw those boxes across the board, like in their example image, it doesn't take a second thought, it's "obvious" (to me anyway), that those are the "lowest, per class".
Yeah, that's why I described it as an examples of a bad design choice that may be accidental rather than a dark pattern. I do still think it's misleading, though.
