The airline was forced to comply with FAA inspections of its MD-80 fleet, leaving over 3,000 flights grounded.
The airline's chief executive has taken full responsibility for the groundings and will hire a consultant to help it comply with Federal Aviation Authority safety rules in future.
He said that the groundings will cost the airline tens of millions of dollars.
Hundreds of thousands of would-be passengers were affected by the canceled flights. We're glad to see that things are finally resolved.
