Beattie Communications, Paratus Communications and Trimedia have been shortlisted for the UK-wide account.
The agencies made the cut after a series of chemistry meetings last week. Pitches will now take place and a decision is expected next month.
EasyJet's in-house PR team will continue to handle the press office function, while the new agency will focus on travel features, sponsorships, stunts and raising the airline's profile across the regions.
As part of the new arrangement, easyJet will dispense with the services of Scottish agency Profile Plus, which was brought on board to drive awareness of the airline's flights in Scotland (PRWeek, 14 May). Its 12-month contract will be terminated after the new agency is appointed.
Separately, Virgin Atlantic has entered phase two of a campaign against the proposed merger of British Airways and American Airlines.
A 'Monster Monopoly' website launched this week outlines the reasons Virgin Atlantic believes the merger would be a bad thing for consumers.
It also urges consumers to write letters of complaint to the European Commission and the US Department of Transportation.
Virgin's in-house team, led by director of comms Paul Charles, will target the national business pages alongside travel trade press.
