Air peace's boeing 777 300 aircraft arrives to open new routes

I think there may be some confusion here!

Air Peace is a Nigerian airline, and while they have been expanding their fleet and routes in recent years, they do not operate the Boeing 777-300 aircraft.

According to Air Peace's fleet list, they operate a mix of Boeing 737-500, 737-700, and 737-800 aircraft, as well as the Embraer ERJ-145 and Bombardier CRJ-900. They have also announced plans to introduce the Airbus A320neo and A330-300 aircraft to their fleet in the future.

It's possible that you may be thinking of another airline that has introduced the Boeing 777-300 aircraft to their fleet. Could you be referring to a different airline or route? If you have any more information or clarification, I'd be happy to try and help!
