US Airways reportedly made a merger offer to American Airlines on Friday.
According to the Phoenix Business Journal, the Tempe-based carrier made the offer after management cut deals with American's unions.
American Airlines Pilots' Association President Keith Wilson said the merger would benefit the airline, which is coming out of bankruptcy.
"It's been proven by Delta and the United corporations and we believe American needs to go stronger and larger faster than it can alone and we think the merger is the best path to make that happen," he said.
Wilson said his union did not hold meetings with US Airways, but hopes to do so in the near future.
The combined carrier would be based in Fort Worth, Texas and fly under the American banner.
Should the merger go through, the resulting airline would likely be the largest in the world.
