Lower fuel prices are helping United Airlines earn record profits despite a dip in revenue.
But the airline is predicting a key revenue figure will fall in the second quarter. And it's speeding up changes to its fleet, including retiring more small planes.
United Continental Holdings Inc. said Thursday that first-quarter net income was a record $508 million, compared with a year-ago loss of $609 million.
Excluding items, United says it earned $1.52 per share. Analysts expected $1.44, according to FactSet.
Revenue fell 1 percent but spending on fuel fell 36 percent — more than $1 billion.
United says a key revenue figure will fall by 4 to 6 percent in the second quarter due to the strong U.S. dollar, lower fuel surcharges and less travel by energy-company employees.
