NEW YORK (Kyodo) Delta Air Lines said Tuesday it will cut its flight services between the United States and disaster-stricken Japan by 15 to 20 percent until May, in response to a decline in demand.

Delta estimates the disaster will reduce its revenue by as much as $250 million to $400 million. Last week, Delta announced it would temporarily suspend daily flights from Los Angeles and Detroit to Tokyo's Haneda airport — inaugurated in late February — from Wednesday.

Delta said it will continue serving Tokyo through Narita International Airport, a hub airport for Delta, as well as Osaka and Nagoya. It will also fly charter flights if demand picks up in the period until May, it said.
