U.S. airlines plan to comply with a Chinese government demand that they revise their website identifications of Taiwan to reflect China's claim on the island territory, said a person familiar with the discussions.

The U.S. carriers affected by the mandate — American Airlines Group Inc., Delta Air Lines Inc., United Continental Holdings Inc., and Hawaiian Holdings Inc. — will begin to change the Taiwan references over the next day or two, said the person, who asked not to be named because discussions among the carriers were private.

The four airlines had been hoping for a negotiated resolution between the U.S. and Chinese governments ahead of China's July 25 deadline. Other airlines, including Qantas Airways Ltd., Air France-KLM and Deutsche Lufthansa AG, have already cooperated with China's wishes.
