I hope Mr. Delta doesn't mind me posting this information. It's from a internal memo and explains the decision to buy the refinery:
"While Delta continues to build momentum, one of the challenges we face is the impact of high fuel costs on our business. Jet fuel cost Delta more than $12 billion last year and crack spreads, the premium we pay refineries for jet fuel, were $2 billion of that amount. We have seen more than $3 billion of fuel cost increases in the past 18 months.
In the face of historically high fuel prices, we have taken a number of steps to control costs since 2008 including creating an integrated Fuel team, retiring less-fuel efficient planes, installing winglets, strictly managing capacity, using fuel hedges and pricing our tickets to reflect the cost of fuel. But the reality is that crack spreads are the fastest growing part of our cost structure, more than tripling over the last three years.
Today we announced that through a separate subsidiary, Monroe Energy LLC, we have acquired from Phillips 66 an oil refinery south of Philadelphia . We will modify the plant to increase jet fuel production and that fuel will be used for our operations. Net of $30 million in government assistance, we will invest $150 million to acquire the Trainer refinery from Phillips 66 and $100 million to maximize the amount of jet fuel it creates. The Trainer facility will operate separately from Delta through Monroe Energy, overseen by a board of directors and led by a team of experienced refinery managers and operators.
As part of this initiative, we will also enter into strategic partnerships with two of the world’s leading energy companies. BP will supply the crude oil to be refined at Trainer and BP and Phillips 66 will exchange the gasoline, diesel and other non-jet fuel products from Trainer for jet fuel in locations throughout the country. The production at Trainer, combined with the jet fuel received from our partners, will account for 80 percent of our domestic jet fuel needs."
So, when a company spends $12 BILLION dollars a year in fuel expense it's easier to see how removing the middle man can be profitable.
