Airbus SE is closing in on a sale of widebody aircraft to Ethiopian Airlines Group and is set to announce the deal on the third day of the Dubai Air Show, people familiar with the talks said.

The two sides are negotiating the purchase of about 10 A350-900 widebody jets, with an announcement possible on Wednesday morning, said one of the people, who asked not to be identified discussing private deliberations. Airbus and the airline declined to comment. The accord has not be signed and elements of the deal or timing could still change, the people cautioned.
