Passengers of Kingfisher Airlines suffered severe hardship on Saturday as the beleaguered carrier cancelled several flights from some key cities and completely shut down operations from Kolkata, including international flights, for about 10 days.

Travel agents and airport sources said that at least five flights from Delhi, including three to Pune, and another six flights from Mumbai were cancelled on Saturday. There was no flight operation from Kolkata, which has seven daily flights, including one each to Dhaka and Bangkok.

The Airlines spokesperson was not immediately available for comment.

Kingfisher's services to Singapore were also affected as its website showed there were no flights available for the next 10 days. The same was the case for Bangkok.

In Hyderabad, the cash-strapped carrier has three flights to Bangalore, Chennai and Vijayawada on scheduled cancellation.

30 aircraft grounded

Maintaining that most of the stranded passengers at various airports were accommodated in other airlines, airport sources said over 30 Kingfisher aircraft were grounded.

The airline was operating only about 160-180 flights out of its already curtailed winter schedule of 240. The sources said operations from Tier-II and Tier-III cities were likely to be affected until March-end.
