Flew KQ in May from Amsterdam to the Comoros (a very very odd place). With just a connection in NBO on the outbound, but connections in TNR and NBO on the way back (odd routing...). Our flights were all on time, but did notice that the days before our return flight many flights were cancelled (incl. the flight the day before ours) and/or significantly delayed departing from HAH (and TNR). Flights were also quite empty so that may be a reason they cancel the flights rather often.
