Southwest Airlines says it will investigate maintenance reports as it feuds with its mechanics' union over canceled flights. The airline, which has been negotiating a contract with its mechanics since 2012, said the number of planes taken out of service due to unexpected maintenance issues has more than doubled the normal 20 out of about 750, in recent days.
