Kenyan Airways has regretted the disruption of its flights last week after the airline’s pilots withdrew "goodwill” that requires them to work voluntarily for certain hours outside their normal schedules, the Post of Zambia reported on Tuesday.Last Friday, Kenyan Airways passengers were stranded at two of Zambia’s international airports due to disruptions. Kenya Airways Manager in Zambia Rose Kiseli said the airline regretted the interruption and has assured customers that the airline has resumed its normal operations. "We wish to regret the interruption of our operations which inconvenienced our esteemed customers. However following the fruitful meeting between our management and the pilot union, the matter was resolved and we have resumed our normal operations,” she was quoted as saying. "Goodwill” is an arrangement by pilot to be available for voluntary work for certain hours during their time off work but within legal limits as approved by the Kenya Civil Aviation Authority, the Post said.
