The flights, scheduled to operate between 25 April and 13 May, will be available to Britons seeking to return home from around the world, via the UAE.
"The special schedule of flights gives foreign nationals in the UAE the opportunity to travel out of the country," said Etihad.
They will also allow the Gulf carrier to repatriate UAE nationals, and ship perishables, pharmaceuticals and medical supplies back to Abu Dhabi.
Flights will be available through etihad.com, the Etihad app, or via local travel agencies.
