Strikes planned by thousands of Heathrow airport workers later this week have been called off so they can vote on a new pay offer.
Around 4,000 members of Unite, including security guards and engineers, were due to walk out on Friday and Saturday, hitting flights on one of the busiest weekends of the summer.
The union said it was not revealing details of the offer until its members had considered it.
Two more 48-hour strikes from August 5 and 23 remain until the result of a ballot of workers is known, added Unite.
A Heathrow spokesman said: “We are pleased that Unite have decided to put our offer to our colleagues and to pause industrial action on 26 and 27 July. We welcome this outcome, as will thousands of passengers, whose holidays will now go to plan this weekend.
“The proposed deal provides significantly above inflation pay rises for all colleagues. We believe this offer is rewarding and importantly gives our colleagues long term wage certainty and job security.
“Passengers are advised to keep in touch with their airlines for the latest information on their flight and follow our Twitter and Facebook accounts for further updates.”
Heathrow said its latest offer is worth 7.3% over two-and-a-half years, adding that the basic starting salary of the airport’s new security officers is £23,153 excluding additional allowances such as shift pay and bonus payments
The pay package is above RPI inflation, higher than the pay increases recently offered to public sector staff and Heathrow’s own managerial staff of 2.4%, said Heathrow.
The airport added it will operate throughout any industrial action in accordance with Department for Transport and Civil Aviation Authority regulations.
