Striking workers from Aerolineas Argentinas (AA) Monday blocked the road to Ezeiza, the country's main international airport after the company fired 168 pilots and mechanics.
Hundreds of passengers had to walk with their luggage for more than a kilometer to reach the airport because of the pay strike which has entered its fifth day at the AA, owned by the Spanish consortium Marsans.
Around 300 flights have been cancelled and more than 24,000 passengers affected due to the strike, which was called to press their demand for pay rises, better working conditions as well as the reinstatement of 11 sacked workers.
The labor unions of the Aeronautical Technicians Association (APTA) and the Association of Airline Pilots want a 45-percent pay rise for their members, but the company is only offering 5 percent.
Five unions representing other AA workers did not support the strike. They demanded on Monday the resignation of the deputy transport secretary and leader of the air crew union Ricardo Cirielli.
"We want to see Cirielli relieved of his post because we believe he cannot be a government official and at the same time organized a strike that leaves 8,500 out of work," said Alicia Castro, leader of the stewardesses union.
