Despite its reputation as the fun and cheap airline, Southwest now finds itself with the highest-paid pilots in the business. And, reports Reuters, those pilots may take a haircut on their next contract negotiation.

The problem is that the fuel hedges are about to run out and that money was a great part of the company’s revenue. In fact, it was $225 million out of a net income of $333 last year.

Southwest is figuring where it can trim costs to produce profits when that hedge money stops rolling in and the pilots checks offer a fat target. Even the union says higher pay is not the top priority. No one expects a strike but a recent stab at getting more hours per pilot backfired when it cost a whole lot more overtime.

Just in case you wondered, Southwest pilots make $186 an hour, according to JPMorgan. American is the next highest payer at $161 an hour.
