These may be simple glimpses at the design, but a full reveal isn't possible because the uniforms aren't finished finished. Select JetBlue crew are currently wear-testing the garments in preparation for final tweaks. The completed looks are scheduled to fly on all crew beginning in spring 2014, around the time the airline will receive the snazziest of their new A321s with lie-flat "suite" seats.
Aside from more "futuristic" designs and a greater variety of accents (such as the patterns of men's ties), the most notable change is the introduction of female pilot uniforms.
If you're lucky enough to be onboard a JetBlue flight with a flight attendant sporting the new faux-wrap dress (with a flash of orange), be sure to throw out a compliment on the new look and, just maybe, they'll throw an extra bag of Terra Blue Chips right back at ya.
