 Pacific Southwest Airlines billed themselves as the friendliest airline around and painted smiles on their fleet in the early 1970s. They were also known for the uniforms of their flight attendants which included hot pants. Here a bevy of smiling flight attendants pose with a new Lockheed L1011. Friendly or not, the L1011s were never profitable and were soon grounded . The airline saw a lot of changes as they diversified into unrelated businesses in an attempt to become profitable. By August of 1976, the hot pants were gone too. The airline struggled along and deregulation did them no favors. The airline was sold in 1988 to American Airlines.
