ATLANTA — Delta Air Lines’ financial results for the December quarter and full year 2016 included $923 million adjusted pre-tax income for the December 2016 quarter, a $524 million decrease from the December 2015 quarter, primarily driven by the new pilot agreement, said Delta.

For the full year, adjusted pre-tax income increased 4% year-over-year to $6.1 billion. Delta employees were told they would share over $1 billion in profit.

“Delta had a year of record-breaking performance in 2016 – financially, operationally and for our customers – and it’s an honor to recognize our employees’ efforts this year with over $1 billion in profit sharing,” said Delta CEO Ed Bastian.

“As we move into 2017, we are seeing our unit revenues turn positive which should return the company to margin expansion by the back half of the year.  This will allow us to produce the solid returns and cash flows that investors rely upon from Delta,” he added.
