"The airlines' chief information officer Saurav Sinha, flight operations head Capt Ronald Nagar and cabin crew head Ajit Bhagchandani have put in their papers recently," Kingfisher Airlines sources told PTI.
Their resignations come close on the heels of KFA's executive vice president Hitesh Patel and ground handling chief Murali Ramachandran reportedly parting ways with liquor baron Vijay Mallya's grounded airline.
The private carrier, which has not paid its employees since August last year, has been grounded since October. Its air operations permit or the flying licence lapsed on December 31 last year, although it can be renewed within two years.
"Besides these executives, a few pilots and engineers have also quit the carrier in the last one month as they did not see any hope of its revival," the sources said.

Meanwhile, Kingfisher Airlines' Mumbai-based pilots are planning to revive their agitation over non-payment of salary and are likely to hold a meeting here tomorrow to chalk out their action plan, sources said.
"Our July 2012 salary was paid in March and since then we have not received any payment. The management is keeping quiet on when it will pay our dues. We have called an internal meeting on Monday to chart out our course of action," an airline pilot said.
State Bank of India (SBI) said last month that the consortium of lenders has recovered Rs 800-1,000 crore and is making all efforts to recover the remaining dues from the airlines.
The consortium of 17 banks, led by SBI, has an outstanding of over Rs 7,000 crore from the carrier.
