Flight from Aeroparque airport in Buenos Aires were delayed on Friday, as aviation sector workers carried out minor strike activity in protest over lay offs and salary stagnation.
Ten flights were delayed and some airlines were considering cancellations as a result of the Aeronavegantes union's decision to hold assemblies aimed at discussing broader strike action.
Friday's move involved staff at the smaller nationally-owned carriers FlyBondi and Andes. However, the assemblies were interrupting flights from all airlines operating out of Aeroparque.
Inflation in Argentina is expected to surpass 40 percent in 2018, prompting concern among unions across all sectors about real wage loss.
Argentina's commercial travel sector also is experiencing a shake-up with the growth of low-cost tourism.
Over 630 new routes were granted to 13 companies in tender processes during 2017. FlyBondi and Norwegian Air are two of the newcomers which are already operating in the country.
Unions say low-cost travel will impact conditions and safety standards for workers and passengers.
