Around 12 Kingfisher flights were on Friday cancelled after the pilots reported sick in protest against non-payment of due salaries.
Ten flights from Delhi and two from Mumbai were cancelled after pilots did not report for work, sources said.
Pilots have been protesting since Thursday against non-payment of their due salary.
Sources said a section of Kingfisher pilots have got their due salary, especially the co-pilots but the captains have not been paid.
According to the pilots, they were assured by the management that their salary for the month of January will be paid by May nine but it did not happen, due to which they started reporting sick.
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.
