Gatwick baggage security screeners have postposed strikes but action by special assistance personnel is still due to go ahead.
An improved pay offer by security service provider ICTS has led the Unite union to calling off action on July 12-14 and July 19-21.
Staff will be balloted on the revised pay proposal but the union warned that fresh industrial action will be scheduled if the offer is rejected.
Strikes on the same dates by 200 workers who offer special assistance services for vulnerable passengers employed by provider Wilson James are set to go ahead.
Unite regional officer Dominic Rothwell said: “As a sign of good faith, ICTS workers at Gatwick have postponed strike action while they are balloted on the new offer.
“Industrial action by Wilson James workers can also be avoided but only if the company comes forward with an improved deal.”
