Emirates Airline is increasing capacity on flights to Dar es Salaam by 40% following British Airways' decision to withdraw from the city.
BA will stop operating its thrice weekly service from London Heathrow airport to the Tanzanian capital on 31 March, as part of its revised summer 2013 schedule.
"The flights are being suspended because they don't make a profitable contribution to our business," a spokesperson for the UK flag carrier says.
Effective 1 February, Emirates will replace the Airbus A340-500 currently deployed on its daily route from Dubai to Dar as Salaam with a larger Boeing 777-300ER, boosting seat capacity by 40%.
The new aircraft has 360 seats in a three-class configuration, comprising eight first class suites, 42 business class seats and 310 economy seats.
"Dar es Salaam is one of east Africa's most popular destinations and the introduction of the new Boeing 777 is a direct response to increasing passenger demand on this route," says Jean Luc Grillet, Emirates senior vice-president, commercial operations for Africa.
"Emirates carried 148,000 passengers on flights to and from Dar es Salaam in 2012. With the new Boeing 777 service we expect this to noticeably grow."
