The partnership will see the Avis, Budget, Maggiore and Zipcar brands offered across the various Etihad booking channels worldwide.
The airline says Etihad Guest members will benefit from the Avis Preferred programme and an improved earning proposition.
Etihad Airways Vice President Commercial Partnerships, Yasser Al Yousuf, said: “We are delighted to embark on this new partnership with Avis Budget Group. This partnership gives our guests a seamless travel experience door to door.
“We chose Avis Budget Group as an exclusive partner for their wide-ranging fleet of cars and their global reach, which suits the needs of our guests and plays a big part of our ‘Choose Well’ campaign empowering customers to make their own choices.”
Avis Budget Group’s Director of International Sales and Partnerships, Julia Kemp, said: “We are delighted that we have extended our partnership with Etihad to be the exclusive global mobility provider.”
“The partnership is far-reaching and there are wonderful opportunities across all facets of the Etihad Aviation Group. As well as offering deals on Avis Budget Group car rentals, we will be looking at tri-party campaigns with hotels, tourist boards and credit cards.”
To launch the new partnership, Etihad Guest and Avis Budget are offering Etihad Guest members the chance to win flights for two, with Etihad Airways anywhere across the Etihad network and seven days car rental.
