The Gulf carrier previously announced five flights back to Heathrow from late-April up to mid-May, allowing Britons to return to the UK via Abu Dhabi.
Additional flights will now operate on 16, 20, 23, 27 and 30 May as Etihad "prepares for an eventual return to scheduled flights".
All flights are being operated under stringent health and safety guidance, adhering to social distancing, and are subject to rigorous pre-flight cleaning regimes.
Other routes include Amsterdam, Barcelona, Brussels, Frankfurt and Zurich. No further Dublin flights are planned though.
Fares are available from the Etihad website and app, or by phone or local travel agency.
