The Vijay Mallya-owned carrier could face more trouble as its Mumbai-based pilots have also decided not to fly from tonight, sources in the airline said in Mumbai.
The pilots of the cash-strapped airline are protesting the "backtracking" by the management on its "assurance" of remitting their January salaries from May 9.
The cancelled services from Delhi include flights to Shimla, Dehradun, Dharamshala and Jaipur--routes operated by turboprop aircraft.
"The management had said that it would start giving January salaries from May 9 onwards. However, it has backtracked on its commitment," Kingfisher sources told PTI.
"So the Delhi-based pilots decided to report sick from today at a meeting last night," the sources said.
The Kingfisher Chairman Vijay Mallya had "assured" the staff in his May 5 communication to them that their January salaries will be remitted from May 9.
Last month also, Kingfisher management had said it would pay employees' December salaries between April 4 and April 9 in a phased manner, but some of the employees recieved their salaries as late as around April 24, the sources said.
A section of the staff including pilots and engineers had last week said they were contemplating moving to the Labour Court to seek its intervention and expedite settlement of their dues.
Kingfisher Airlines has been facing financial troubles for almost a year now. The airline, which never made a profit since its inception in May 2005, reported a net loss of Rs 444.26 crore in the December quarter.
It suffered a loss of Rs 1,027 crore in 2010-11 and has a debt of Rs7,057.08 crore.
Due to the paucity of funds, the air carrier now operates only 110 flights a day with a fleet of 20 aircraft as against 400 flights per day last year with 66 planes.
The airline had a 6.4 per cent market share in March, and was ranked below the budget carrier GoAir, which cornered 7.5 per cent market share in the same period.
