FORT WORTH, Texas — American Airlines’ parent company, now in bankruptcy protection, says its stock will be dropped from the New York Stock Exchange.

Shares are sinking 18 cents, or 35 percent, to 34 cents in after-hours trading.

AMR Corp. said Thursday that the NYSE notified the Fort Worth, Texas, company of the move after the average closing price of AMR shares fell below $1 for 30 straight trading days.

The shares will stop trading before the opening bell next Thursday. The delisting includes AMR common stock and some company-issued notes.

AMR filed for bankruptcy protection on Nov. 29.
