Kenya Airways has raised its weekly flights on the Nairobi-Kisumu route from 25 to 34.
It has announced an additional daily flight in the morning and evening to meet growing passenger demand.
KQ managing director Titus Naikuni said the move by the airline is in line with the needs of the growing middle class in the country.
"As Kenya enters the era of a devolved system of government there is an increased need for robust transport network linking up different parts of the country," said Naikuni.
Following the changes, the last flight of the day will now be leaving Nairobi's Jomo Kenyatta International Airport at 1830 hours daily with the return flight leaving Kisumu International Airport for Nairobi at 0715 hours
