Hertz Global Holdings Inc. (HTZ +7.26%) has tentatively agreed to shed about a dozen locations at U.S. airports in a concession aimed at winning U.S. regulatory approval for its proposed acquisition of rival Dollar Thrifty Automotive Group Inc., (DTG +5.40%) according to people familiar with the negotiations.

By offloading airport locations, Hertz aims to allay Federal Trade Commission concerns that a combination of the rental-car giants could hurt consumers by giving the joint company too much control over the rental-car market, particularly at airports.
