The question is what kind?
From Kenya Airways' unaudited interim results:
"... the Company is committed to continued expansion with new routes starting to Paris on 26th October 2006 and Mayotte/Comoros on 16th November 2006. Additionally, a fourth new Boeing 777 is due for delivery in February 2007 to facilitate further expansion on existing routes and the Board have decided to replace the current fleet of two Saab aircraft with regional jets."
I hope they get E170's though there is no indication of what they will get. Whatever, they choose will be a great addition.
