A 24-hour strike planned at Glasgow Airport in the lead up to Easter has been suspended.
The action was due to take place on Tuesday after Unite members at the airport in a row over pay and pensions.
In a ballot this month 95% of those who voted backed industrial action.
However, a joint statement from Unite, Prospect and AGS Airports said progress had been made during discussions at Acas on Friday and Monday.
Workers voted in favour of action scheduled over the spring and summer months amid a row over what Unite described as a "paltry" pay offer and the proposed closure of the airport's final salary pension scheme.
AGS Airports also owns Aberdeen International Airport, where a similar dispute is taking place.
The joint statement released on Monday said: "Progressive talks have been conducted on pay which saw the company table an offer of 3% for Aberdeen International and Glasgow airports.
"This was met positively by the trade unions.
"No agreement has been reached on the company's proposals regarding the DB pension scheme, however, the company is supportive of the trade unions' request to continue dialogue involving the chief executive of AGS, Derek Provan.
"The pension scheme consultation, originally scheduled to close on April 14, has been extended to accommodate the further discussions and talks will be scheduled in the coming days. The proposed closure date of May 31 will be extended.
"Through talks at Acas, the industrial action planned for Tuesday April 16 at Glasgow Airport has been suspended."
