There are MANY factors that will spark a livery change, and don't underestimate the signal being sent by new management. (and the CEO's wife liking mauve). Delta doing 3 programs within just a few years, each with management changes (I lived through 2 of them) Wolf wanting United Airlines to look like
AF One, and doing Battleship because of his belief that it would make United more serious looking than the Saul Bass livery (mr Bass was inspired by the beautiful sundown horizon line across the grey clouds. (most obvious on the old carpeted bulkheads, and the rainbow coach seats) The cheat lines were actually Blue, orange and magenta, offset by grey
ALL brands update their design, from a bottle of Gatorade to an airline. The big move is when the LOGO (SYMBOL) is changed or created. Like, Cathay creating the Brushwing logo when the previous Cathay had no logo. (frankly United needed one badly, so mr Bass developed the "flying U" (or tulip)
There are updates to logos, where the subject matter of the logo is kept but the design of it changes: VARIG has a compass that looked like it was created in the 1950's, Landor kept the compass idea, but created a totally new one that reflected something far more Brazilian. It was both a "sun" and a "compass" (a compass was a nod to Portuguese leadership over the seas and navigation hundreds of years ago) and good use of Blue and Yellow without looking like a "futebol" 747! As for the ...Pan Am globe (IMHO was the best logo ever, out of any logo on earth- ever). it still stirs the heart today. Pan Am fashion is vogue because of that sky blue GLOBE!
Great brand stewardship comes from truly understanding your brand and "branding" (the signals of your brand). Arguably the
SQ Crain is a dated design done by Walter Landor in the 1970's. They know their brand is delivering consistency, a consistent level of unrivaled excellence. Therefore they don't change the symbol, ever. They can update the colors, the livery, but NOT the sacred symbol. Same with Thai. They have changed the "stripes" a lot to reflect a new, fresh brand promise, but, they dare not touch the symbol. (United feels uncomfortable because it isn't clear)
I assume, (hope) QANTAS never fundamentally changes the Kangaroo, but I can see them update how it is depicted one day.
The look of design all around us changes
ALL THE TIME the same way clothing and how clothing marks eras. The impact of digital on design was unprecedented. A whole new world opened up since the 1990's and it drove major changes to the fundamentals of branding, from names to design. (Google, Apple)
The
CO livery is the PRIMO example of that. That digitally created globe was driven by new technology of the day, the new look that the digital world introduced. It basically made everything pre-1990 look dated. I think the current United look (which has a very bad symbol) is dated because it looks like early digital looking design. (it's fine for now because until
UA figures out who they are and fixes the promise they make to their fliers, they shouldn't change)
As generations turn, as young adults today have grown up with an entirely different sense of aesthetics, so has the need to update. From a can of Coke to the tail of a 787.
