DALLAS (AP) -- Directors of American Airlines and US Airways (NYSE:LCC) reportedly plan to meet Wednesday to consider a merger.

The Wall Street Journal reported Monday that negotiators were still considering the makeup of the combined company's board and an exact role for the CEO of American parent AMR (NASDAQOTH:AAMRQ).

US Airways declined to comment, and AMR did not return messages.

The companies are trying to finish a deal before Friday, when a confidentiality agreement covering some AMR bondholders expires. That could result in public disclosure about negotiation details.

If the two carriers were to strike a deal, it would create the world's biggest airline by passenger traffic, although United Continental Holdings (NYSE:UAL) would still be bigger if regional affiliates are counted.

AMR has been operating under bankruptcy protection since November 2011.
