Ethiopian Airlines resumed Boeing 787 Dreamliner today revenue service with a flight from Addis Ababa to Nairobi, making it the first carrier to relaunch Dreamliner flights since the aircraft was grounded in January.

Ethiopian Airlines CEO, Tewolde Gebremariam and Boeing VP marketing Randy Tinseth, Boeing were onboard the flight. Ethiopian has four 787s and was the first African carrier to order the aircraft. It originally began 787 service in August.

Last week, FAA certified solutions proposed by Boeing to address issues related to the aircraft’s lithium ion batteries.

Other airlines are preparing for their 787 service resumptions. All Nippon Airways (ANA), the Boeing 787 launch customer and largest Dreamliner operator with 17 in its fleet, will conduct a 787 proving flight Sunday, an initial step toward resumption of commercial flights with its 787s. The Japanese government approved Boeing’s fix Friday for the 787’s battery system.
