Braniff Inc. was a US-based airline that operated flights from 1984 until 1989 and was partially formed from the assets of the original Braniff International Airways. The domestic air carrier was originally headquartered at Dallas Love Field in Dallas, Texas, and later Orlando, Florida. The airline is sometimes referred to as "Braniff II".

Pacific Southwest Airlines (PSA) was a low-cost US airline headquartered in San Diego, California, that operated from 1949 to 1988. It was the first substantial scheduled discount airline. PSA called itself "The World's Friendliest Airline" and painted a smile on the nose of its airplanes, the PSA Grinningbirds. The Los Angeles Times called PSA "practically the unofficial flag carrier airline of California for almost forty years."
