Ex BN here. The first BN went under May 13, 1982. The relaunch of BN2 occured on March 1, 1984 with the slogan, "Were building the new Braniff around you." In November management switched when William Slattery left as president of the company and Ron Ridgeway took over. Fare structure went from full fare to discount airline, cities slashed from 21 down to 9, and the slogan, "Best low fare in the air was introduced in November of 1984, shorten to "Believe it," around 1986. Hyatt sold thier interest in BN in 1988 to a crook named Jeffery Chowdrow who along with a friend "Scott Spence," looted the company. BN ceased operations in September of 1989, resumed operations as BN 3 in July of 1991 with a retread slogan from the 70s, "Braniff gets you there with flying colors." Ceased operations in July of 1992. I gave up with BN2 and have been happy with CO since then.
Here is the jingle used with the "Believe it," slogan.
You can believe in Braniff, believe in what we do. Were proud to say were Braniff. Were proud to be serving you. Were hard at work, to be the best, from coast to coast and to all the rest. You can believe in BRANIFF!
