New Delhi: Shares of Jet Airways tumbled nearly 5 per cent Thursday as the company delayed part payment of August salaries to pilots and senior management personnel.

Also, the decision to impose 5 per cent customs duty on ATF also hit sentiment.

Crisis-hit Jet Airways has told its pilots, aircraft maintenance engineers and senior management team that part of their August salaries will be paid by October 9, according to a communication.

On September 6, the full service airline told senior employees that salaries would be paid in two installments till November.

The salaries for August were to be paid in two instalments -- 50 per cent by September 11 and the remaining by September 26.

Experts say that the latest decision to impose 5 per cent customs duty on ATF, which is a major component of an airline's operational costs, would add to the woes.
