Jet Airways on Thursday suspended its international operations for a day and grounded its services to the East and Northeast regions. The drastic initiative was announced after the airline informed the exchanges that it was forced to ground 10 more planes due to non-payment of rentals to the lessors. "Jet Airways flights to London, Amsterdam and Paris from Mumbai, New Delhi and Bengaluru scheduled for April 12 are cancelled for operational reasons," said an airline source close to the development.
