The nation’s second-largest airline says it will lose between $250 million to $400 million this year due to the crisis in Japan. Due to that and higher fuel costs, Delta is again scaling-back its flight schedules.

The airline says it will cut its flight schedule to Japan by up to 20 percent through May because of slower demand as the country recovers from the earthquake and tsunami. That includes the suspension of two new flights to Tokyo.

And Delta is not alone in dealing with rising fuel costs. The Atlanta-based carrier and other airlines including United and Continental have steadily raised fares this year, as the price of oil is up nearly 40 percent since Labor Day.

For the second-half of the year, Delta now says it will reduce its flights worldwide by 4 percent, with the biggest reductions on routes to the Pacific.
