Airbus A320 (N467UA)

UAL's "Ted" subsidiary did not last very long. It began operating in 2004 and was discontinued just five years later in 2009.
Ted was launched by UA as a low cost subsidiary. It was primarily started to compete with low cost carrier Frontier. (Delta did the same thing at around the same time when it launched its own low cost subsidiary "Song" to compete with low cost carrier jetBlue.)
By the middle months of 2009, the aircraft in Ted's fleet (all Airbus) had been assimilated into UA's regular fleet and the Yellow Tulip livery seen in the photo above was gradually replaced by the standard Blue Tulip livery being used at that time. Of course, it was only a few years later when United merged with Continental and the Blue Tulip on the tail was subsequently replaced with the gold Continental tail design, which is now being replaced by the newest tail colors.
Sort of makes a person wonder how much $$ United has paid out for paint over the past 20 years (grin).
