African low-cost carrier Fastjet saw February carryings from its Tanzanian operations rise by 50% to 52,801.
The airline paid 13% less for fuel in February over the previous month, representing a 37% cut compared to February 2014.
Fastjet achieved a load factor of 70% in the month with 96% of flights arriving on time.
Passenger numbers for the year to February were up by 68% to almost 640,000.
Interim chairman and chief executive Ed Winter said: “With a 50% increase in passengers we continue to see great year on year growth achieved by increased utilisation of our aircraft.
“As we approach Easter and peak summer months we will be adding even more capacity on existing routes and expanding our route network.”
