United Airlines plans to ground 100 of its older aircraft
US carrier United Airlines is to ground 100 of its planes and cut between 900 and 1,100 jobs, in addition to 500 already announced lay-offs.
It blamed the decision on the need to cope with the spiralling cost of fuel and a weakening US economy.
It will also scrap its economy-class only Ted service and reconfigure those planes to include first-class seats.
The planes to be grounded will be 94 Boeing 737s and six of the larger Boeing 747s.
The plan will lead to a 17-18% cut in its domestic capacity and international capacity will be scaled back by 4-5%.
United recently shelved plans to merge with US Airways after months of talks about a cost-saving deal.
Many airlines have been struggling after oil hit a record $135 a barrel and aviation fuel prices surged 76% in the past year.
"This environment demands that we and the industry act decisively and responsibly," said Glenn Tilton, United's chief executive.
"At United, we continue to do the right work to reduce costs and increase revenue to respond to record fuel costs and the challenging economic environment."
In April, the Chicago-based carrier announced it would cut some 500 jobs in an effort to save costs.
The latest move will make a number of salaried, contract and management workers redundant by the end of the year.
Last week, the International Air Transport Association (IATA) warned the airline industry faced a "grim" outlook and passenger numbers would be affected by rising fuel costs and the deteriorating economic situation.
The number of airline passengers grew by 3% in April, down from 5.4% in the same month the previous year, it said.
And for the first four months of the year, growth was 5.6%, compared to 6.7% the previous year.
The airline industry has already seen a number of carriers collapse in Europe, Asia and the US, and only last week UK airline Silverjet went into administration.
American Airlines recently said it would lay off workers and reduce its domestic flight capacity to 12% after the busy summer period in a bid to keep finances under control.
Other airline companies have started charging passengers to check in bags.
