Although Bigmouthmedia's current contract with the airline was due to expire at the end of this month, the partnership was renewed after a repitch in August as part of British Airways' standard procurement policy.
After working with the digital marketing agency for six years since 2002, British Airways cited Bigmouthmedia's expertise as a critical factor in the deal.
Working together with the airline's digital marketing team in search engine optimisation and pay-per-click strategy, the agency will be responsible for planning, implementing and managing paid search campaigns across the UK market.
Earlier this year, Bigmouthmedia was awarded a £5m search account for BT Business' directories following a multi-agency pitch.
Last month, the agency also won the online media account for UK number plate provider British Car Registrations.
