The company is using Agency Assessments International to help with the review, with an appointment expected to be made in January.
Avios’ digital and DM work is currently handled in-house. Its advertising is created by 101, which is unaffected by the review.
Avios rebranded last year after the merger of British Airways and Iberia to form International Airlines Group.
After the rebrand, 101 created a TV ad, "anything can fly", that featured airborne lawnmowers and washing machines.
Agencies that have previously worked with Airmiles on DM include Partner Andrews Aldridge, which was appointed in 2006 to handle an integrated brief.
Avios is a shared currency for the Avios UK reward programme, British Airways Executive Club and Iberia Plus, allowing IAG consumers access to all three schemes. Consumers can collect points through Tesco, Lloyds TSB and Shell, as well as through purchases of more than 200 other brands.
