Delta Express was a no-frills "airline within an airline" brand owned and operated by Delta Air Lines from 1996 to 2003. The airline was headquartered in Atlanta, Georgia.

Ted was one of two airline divisional brands of United Airlines. It targeted vacation locations primarily served by the low cost airline market, in contrast to the company's high-end premium transcontinental brand, United p.s.. "Ted" comes from the last three letters in the United brand name. United marketed Ted anthropomorphically and attempted to personify Ted; it used phrases such as Meet Ted or I've Met Ted.
