Ethiopian Airlines plans to resume flying Boeing 737 MAX flights in February 2022. According to what its CEO said on Monday, the airline is satisfied with Boeing’s changes to the planes.

“Safety is our topmost priority …. and it guides every decision we make and all actions we take,” Tewolde Gebremariam said in a statement.

“We have taken enough time to monitor the design modification work and the more than 20 months of rigorous rectification process…our pilots, engineers, aircraft technicians, cabin crew are confident on the safety of the fleet.”

The Ethiopian carrier grounded its Boeing 737 MAX 8 jets as an “extra safety precaution” following the 2019 crash of flight ET 302 that killed all 157 people on board.
