In the following Aviation Week article, the publisher of Petroleum Economics Monthly says that the DL refinery purchase could result in a significant shift in the NYC market from other carriers to DL due to a cost advantage that could equal 20 cents/gallon or more and would be most significant to DL on long-haul flights, including the highly competitive NYC market

These benefits alone could give Delta a $4,000-5,000 advantage on every flight from Kennedy to London Heathrow Airport, Verleger calculates, and grow even higher should the small number of refineries located on the East Coast use the supply shortage to raise prices.
“I fully expect to see five years from now that a much larger share of the international flights from JFK will be Delta's,” says Verleger. “To really build New York and make it work, you need a cost advantage, and this gives them the cost advantage.”

According to Verleger, Delta's potential competitive advantage compares to Southwest Airlines' hedging policy before the spike in fuel costs that gave it a distinct cost advantage for several years over the many U.S. airlines that did not hedge. “By acquiring the Trainer refinery, Delta may pull off the same feat as Southwest,” Verleger says.

“With Trainer, Delta could match the competition's prices and pocket profits from lower-cost fuel,” he continues. “Alternatively, it could follow Southwest's example and initially pass the cost savings on to consumers. This would force larger losses on other airlines or cause them to exit the market.
“We bet that Delta chooses the latter option,” Verleger says.

The airline adds, “we're making it right in the neighborhood and we'll capture the tariffs we currently pay to pipeline companies to move jet fuel. In that the transatlantic is brutally competitive, every single penny counts.” In other Northeast U.S. locales and with exchanges for jet fuel in other locations, Delta says its fuel transport savings will be significant across the country.

The article also notes the environmental risk should add'l regulations be put into place to require cleaner fuel as well as the downtime necessary at refineries, although it is normal for agreements to exist to cover each other's output during downtime.
