Southwest Airlines has never had the capability to take delivery on crude oil. They buy jet fuel. No Jet Fuel tank at any airport is going to be filled with crude oil.
Sorry I was painting this mess with such a broad brush. Agreed they don’t buy crude oil. But they sure do buy futures on jet fuel, and that is why they are in a much better shape financially because they locked in at a much lower price. When we say crude oil I was thinking of the many finished products.
