The service to Enugu was suspended for two years as the airport serving the city underwent renovation works.
It restarted on 9 October, and flights are now operated on Wednesday, Friday and Saturday, the airlines said in a statement.
Ethiopian is one of the oldest carriers flying to Nigeria and has been serving the country since 1960, strengthening trade, cultural and tourism ties between Nigeria and the rest of the world.
Passengers from Enugu will have direct flight connections to many destinations in Africa, Middle East, Asia, South America and Europe with the vast Ethiopian network and modern fleet.
Tewolde GebreMariam, Group CEO of Ethiopian Airlines, described Nigeria as one of the airline’s “important destinations in West Africa”.
“We are continually improving our products and services to meet our customers’ expectations and the resumption of services to Enugu is key to reach our customers in different parts of Nigeria,” he said.
“We thank the people and the government of Nigeria for their continued support in restarting our service to Enugu.”
Passengers from Ethiopian’s four gateways in Nigeria – Lagos, Abuja, Kano and Enugu – now have the opportunity to fly to more than 130 Ethiopian global destinations in five continents.
Ethiopian Airlines became the first international carrier to fly to Enugu when it commenced flights in 2013.
