JetBlue has named Mullen Lowe as lead creative agency for its new credit card following a review, AdAge reports. Its media unit, Mediahub, was also named as lead media agency for the new card. The card will be issued by Barclaycard and JetBlue on the MasterCard network and follows JetBlue parting ways with American Express earlier this year. Mullen Lowe has served as lead creative agency for JetBlue since 2010, so the appointment is far from surprising. More at AgencySpy.
