Reno Air Leases American’s Gates: Reno Air Inc., the fledgling low-cost carrier, will sublease up to seven gates at San Jose International Airport in California from Ft. Worth-based AMR Corp., the parent of American Airlines, leaving American with two gates at its former hub. The preliminary agreement would also allow Reno to participate in American’s Advantage frequent-flier program. The move pits the newcomer against Southwest Airlines Co., the carrier that turned low-cost, no-frills flights into a billion-dollar airline.
