First one is a "So what, just remove the American Airlines trademarks". They can drop them and say all good, and presumably not get sued again.

Second one is about what Skiplag was doing itself; I.E. cutting into AA's profits. If they continue to do this, the next court case will be much more expensive. Most courts don't like it when you get sued for something and treat it like the cost of doing business, and AA is big enough that I'd count on them bringing suit again.
