Two Air India flights were on Saturday cancelled due to an agitation called by a section of the national airlines' pilots to protest the up to 50 per cent reduction in their productivity-linked incentives (PLIs). According to Air India officials, Air India's flights to Mumbai and Kabul from Delh were cancelled this morning as the pilots did not report for duty. Airline officials said the passengers of the cancelled flight to Mumbai have been accommodated in the next flight while those going to Kabul have been lodged in a hotel.A section of Air India Executive pilots had last night threatened to go on the agitation to protest the reduction in their productivity-linked incentives (PLIs).Representative of Executive pilots Captain Bhalla had said that the Executive pilots have taken a decision to go on strike because nobody is in state of mind to work due to the salary cuts. He also alleged that the Chairman had not discussed the salary cuts with Executive pilots. Official sources said the Executive pilots were taken on board over the PLI reduction and their move was surprising. It said, there are around 300 Executive pilots in the national carrier and since they are part of the airlines management, they cannot form a union and also cannot go on strike.
