The two airlines have been discussing a potential deal for months and sources tell ABC News affiliate WFAA that the board of directors of AMR Corp., American's parent company, will meet on Monday to consider a possible merger.
Nothing has been decided and no actual deal is in place, a source told ABC News. That doesn't mean a deal can't be hammered out between the two airlines.
Both airlines have declined to comment on reports that a merger is imminent. If a deal is reached, the new airline would become the largest in the U.S.
