It is believed that Cake, Band & Brown, Cow PR and one other are fighting to be awarded a one-year contract with the airline.
The chosen agency will be asked to manage the airline’s social media strategy, strengthen its online presence as well as attempting to influence bloggers.
The pitch is being managed by Creative Brief. BMI Baby is expected to select an agency in the next couple of weeks. The airline has worked with digital agencies in the past on a project basis.
BMI Baby is part of the BMI Group and was established in 2002. It operates from four UK bases: Birmingham, Manchester, East Midlands and Cardiff.
