Delta Air Lines

Delta Air Lines on Friday said it is planning to cut service to smaller, under-performing markets.

All of Delta Air Lines’ Boeing 777 and 767-400ER aircraft have been upgraded to include full flat beds in the their BusinessElite cabins, the airline announced Wednesday.

The Federal Aviation Administration levied a $425,000 fine against Atlanta-based Atlantic Southeast Airlines (ASA), alleging the company operated a pair of jets that were “not in compliance with FAA regulations.”

Citing an “increase in jet fuel prices” and “fluctuating seasonal demand, a trio of airlines, including Delta, are planning to cut trans-Atlantic capacity by 7 to 9 percent.

The on-time performance of the nation’s largest airlines improved in 2010 compared to the previous year, according to the Air Travel Consumer Report released Thursday by the U.S. Department of Transportation.

Delta Air Lines is adding a so-called “Economy Comfort” section to all “long-haul international flights,” the airline said Monday.
