The completed merger of US Airways and American Airlines creates the world’s largest carrier: American Airlines Group. It will take two years to combine fleets and workforces.

FORT WORTH — American Airlines emerged from bankruptcy protection and US Airways culminated its long pursuit of a merger partner as the two completed their deal Monday to create the world’s biggest airline.

It’s the latest in a series of mergers that will leave four airlines controlling more than 80 percent of the US market. With less competition, the airlines have successfully limited the number of seats, boosting prices, and returning to profitability.

American’s old parent, AMR Corp., is gone, replaced by the new American Airlines Group Inc.

‘‘Our goal here is to go and restore American Airlines to its position as the greatest airline in the world,’’ said Doug Parker, chief executive. The largest airline as recently as 2008, American struggled through a decade of huge losses and fell behind United and Delta in size. Southwest Airlines joins the other three as the nation’s largest carriers.

For passengers, the merger will not mean many immediate changes. Whether the deal leads to higher ticket prices, the issue at the heart of legal challenges from the government and consumer groups, remains to be seen.

Parker said that because the new American plans to keep all the service currently offered by American and US Airways, the merger will not mean increased prices. ‘‘Airline prices are like prices in other businesses — they track with supply and demand, and we’re not reducing any of the supply,’’ he said in an interview.

Elite members of the two frequent-flier programs will get reciprocal benefits in early January, with other changes being phased in, executives said. The airlines expect to soon be able to book passengers on each other’s flights, increasing the destinations available to customers of both.

It will take about two years to combine American’s fleet and workforce with those of US Airways, Parker said. US Airways will join Continental, Northwest, and other airlines that now exist only in the memories of employees and longtime travelers.

Airline mergers are notoriously troublesome. United has been plagued by computer-network problems since combining with Continental, leading to outages and flight delays. Airlines’ technology systems handle everything from passenger information to weight and balance calculations on every flight. Then there is the difficulty in merging two sets of employees who, in this case, are represented by different unions.

Already the two flight-attendant unions are fighting with each other. The union that represents mechanics at US Airways boycotted Monday’s event because contract talks have been stalled for nearly three years.

Unions at American received Parker like a conquering hero. Their support for a merger led by US Airways executives was a turning point when AMR chief executive Tom Horton still hoped to keep his airline independent. For their efforts, the unions won stock in the new company.

On Monday, Parker made symbolic moves to extend a hand to labor — painting over parking spaces once reserved for executives and asking Nasdaq to inscribe a commemorative opening bell to the employees instead of to him.

‘‘His greatest challenge is keeping positive sentiment on his side,’’ said Vicki Bryan, an analyst with bond-research firm Gimme Credit. ‘‘He’s at the peak of ‘happy’ right now.’’
