The main trade unions representing airport workers employed by Aena and Enaire have put off the strike action originally planned to start on Friday 15 September and given the authorities until the end of the month to reach an agreement to end the conflict.
After a meeting on Thursday evening it was decided that talks between unions, the firms Aena and Enaire and the government would resume on Tuesday 12 September.
Union representatives said on Thursday night that they were optimistic and that their "perspectives [on a deal to end the conflict] are very favourable".
However Francisco Javier Casado, of the union Comisiones Obreras (CCOO), said that if no agreement is reached before the end of September a strike, which this time could not be postponed, would be called for the end of October.
The workers had originally announced strike action affecting all Spanish airports on 25 dates this autumn, starting on 15 September.
The unions a calling for the employers to make up for the workers' lost spending power in recent years, a sum they calculate to be around 8%.
They are also calling for more staff to be taken on to replace workers who have retired or taken early retirement: 250 in Enaire and 450 in Aena.
Workers' representatives maintain that the time has come for them to benefit from the good results of the firm, which have allowed them to reduce airport taxes.
