MUMBAI, April 14 (Xinhua) -- India's struggling airline Jet Airways continued to hold back bookings on international flights including those to Colombo, Kathmandu, Singapore and Hong Kong till further notice, airline ticketing sources said Sunday.

The debt-ridden airline has earlier cancelled all international flights till Monday.

The airline is struggling with non-payment of lease rentals for aircraft, non-availability of fuel, and non-payment of salaries to staff amid severe cash crunch.

The beleaguered airline's fleet has dropped to 14 from its peak of 119 prior to December.

Meanwhile, over 1,000 pilots of the airline decided not to fly from Monday in protest against non-payment of salary dues since January.

"All 1,100 pilots of NAG (National Aviator's Guild) will stop flying from 10 a.m. Monday," said an office bearer of the pilots' body NAG.
