The airline's move to cut perks and discounts tied to its contracts with corporate travel agencies and clients backfired, hurting its image and giving its peers an advantage.
Since then, it has taken several steps to win back corporate clients.
The company said it renegotiated contracts with travel agencies in the third quarter and many of its corporate customers have reintroduced the airline's benefits program to their business travelers.
"We have taken aggressive action to reset our sales and distribution strategy and reengage the business travel community, which we're confident will improve our revenue performance over time," CEO Robert Isom said.
American's pricing power has also improved as the airline industry cut down excess capacity in the domestic market. It had led many carriers to offer seats at a discount to fill their planes during the summer season, denting their earnings.
Annual domestic seat growth has slowed to 1.5% in October and November from 5.5% in July, according to BofA analysts.
The company expects an adjusted earnings per share of $1.35 to $1.60, compared with its prior forecast of 70 cents to $1.30.
It reported an adjusted profit of 30 cents per share, compared with expectations of 16 cents, according to data compiled by LSEG.
Total operating revenue rose 1.2% to $13.65 billion, above estimates of $13.49 billion.
