NEW YORK ( TheStreet) -- Delta ( DAL) provided one half of the airline industry's total profit in 2012 and is looking ahead to more gains, a result of its New York buildup, fleet strategy and 2012 investments in an oil refinery and Virgin Atlantic. "We are on track to deliver our best March quarter in over a decade," said President Ed Bastian, speaking at the JP Morgan investor conference on Monday morning. The last time Delta had a first-quarter profit, Bastian said, was in 2000, when fuel cost 62 cents a gallon. The cost now is $3.25 a gallon, accounting for more than $2 billion in higher fuel costs during the quarter. But revenue is rising too. Bastian said February passenger revenue per available seat mile will rise 5%. For the first quarter, PRASM is expected to gain 4.5% to 5.5%. A New York buildup is fueling the revenue gains. Bastian said. Delta has gained over seven points of corporate market share in New York over the past three years, leading to a margin gain of more than 300 basis points in New York, he said, noting "We're still in the building phase." The carrier has boosted its capacity at LaGuardia Airport by 45% in the past year, a result of an asset trade with US Airways ( LCC), and it will open a new Kennedy terminal on May 24. Later this year, it will begin a new trans-Atlantic joint venture with Virgin Atlantic after buying 49% of the carrier. That will enable growth in the Kennedy-London Heathrow market, which Bastian said has historically been "our single biggest challenge in corporate customer negotiations" in New York. According to a chart Delta compiled, Kennedy/Heathrow is the No. 1 U.S. international route, accounting for 2.7 million passengers a year. It dwarfs every other route. No. 2 is Los Angeles/Heathrow, accounting for 1.4 million passengers. The next three routes, with 1.2 million passengers annually, are Chicago/Heathrow, New York/Paris and Newark/Heathrow. Interestingly, US Airways does not fly a single one of the top 10 U.S. international routes, largely explaining why it could use a merger with American ( AAMRQ.PK).
