ATLANTA -- Delta is offering passengers a new risk-free cancellation policy.

The carrier said the no-questions-asked plan is good for tickets purchased at Delta.com, Flysong.com, or other direct Delta ticketing locations.

Flysong.com is the Web site for Delta's discount carrier, Song.

The new guarantee will allow customers to cancel certain tickets within 24 hours of purchase without penalty if they find lower fares anywhere else or if their travel plans change.

The policy applies to tickets valid for travel originating in the U.S., Virgin Islands, Puerto Rico and Canada, regardless of where the ticket is purchased.

"Delta is demonstrating to our customers that we are confident our fares are highly competitive, and we promise a customer will always find Delta’s lowest published fares at delta.com," said Paul Matsen, Delta’s chief marketing officer.

Delta has been fighting to stay out of bankruptcy protection.

Just last week, the nation's third-largest airline posted a $388 million second-quarter loss, pushing its red ink to just under $10 billion since early 2001.
