"Delta... They have the most buffer. They own a refinery in Pennsylvania so that provides an operational hedge." While the broader airline industry suffers from spiking jet fuel prices, Delta's ownership of a physical refinery allows it to offset some of the fuel cost increases, giving it a structural margin advantage over its peers during energy shocks. LONG because Delta is uniquely positioned to weather an oil price spike better than other airlines. A severe drop in consumer travel demand due to a recession would hurt revenues more than the refinery hedge helps costs.
