BA said that M&C Saatchi would be invited to pitch for the work and that the decision to review was good business practice, rather than a reflection of the relationship with the agency.
Martin George, commercial director of BA, said: "We have enjoyed a long and successful relationship with M&C Saatchi. Together we have created a reputation for outstanding advertising.
"However, as the airline continues to face the challenges of an increasingly competitive market, we are required to review all our major contracts across the business in line with our corporate procurement policy. This means that we will review our global advertising to ensure it meets the needs of our changing business and that we manage our worldwide account in the most effective way."
George will oversee the pitch along with Jill McDonald, head of global marketing. BA is currently reviewing agency credentials and will invite three or four agencies to pitch against M&C Saatchi for the work. The review is expected to be concluded by the autumn.
Other agencies on BA's roster include ZenithOptimedia, Interbrand, and The Ingram Partnership, which was appointed last month to work on brand strategy.
