It is not a good time for international low-cost airlines.
The bankruptcy of British company Monarch Airlines, with immediate effects on the 34 international routes from British airports, has also involved Kenya in part.
In fact, the tour operator Thomas Cook, who works mainly with Mombasa and the south coast (Diani, Tiwi Beach), but also for savannah destinations, with stopovers in Mombasa and Nairobi, is heavily penalized by the total closure of flights.
Monarch has been bringing UK tourists to Kenya at competitive prices for many years.
Some British and European operators have already supported other airlines in recent months, probably predicting a collapse from one moment to the next.
While flag carriers such as Ethiopian and Qatar continue their expansion and increase flights to Africa and airports, and new lines get licenses to land in Kenya, charter ships seem to have the biggest problems (and not only for long-haul destinations, see Ryan Air). 
The German airline Air Berlin, which provides carriers for the German charter company Condor, is also currently in receivership.
