Check-in workers in Buenos Aires walked out after passengers stranded by a baggage handlers strike rioted on Saturday.
Xinhuanet reported that travellers tossed computers in the air, shoved security guards and attacked ticketing counters at Buenos Aires' Ezeiza international airport Saturday after Aerolineas Argentinas suspended most of its flight there.
Tempers flared as hundreds of travelers awaited word on suspended and canceled flights. Aerolineas Argentinas attributed delays to a labor conflict involving a pilots' union and a union for airport tarmac workers. But union officials said the disruptions were caused by overbooked flights.
Ticketing counters were abandoned in the afternoon after passengers assaulted a worker at a check-in desk, said Maria de los Angeles Aguer, a spokeswoman for the Association of Aeronautical Personnel.
The strike for higher wages had sparked delays at the airport in a Buenos Aires suburb since Friday.
Aerolineas Argentinas is 95 percent controlled by Spain's Marsans, with the remainder held by the Argentine state.
