Unit union has been engaged in lengthy talks with Heathrow officials to avert Tuesday’s strike that would have seen 2,000 staff walk out for 24hours.
A spokesperson for Heathrow Airport said, “Unite has chosen to postpone its strike action on Tuesday 6 August. Strike action on 23 and 24 August is still scheduled to go ahead.
“Unite will now take an improved offer to its members and we remain hopeful that we can find a resolution and stop this disruptive and unnecessary threat of strike action.
“We regret that passengers have been inconvenienced by this and urge them to contact their airline for up to date information on the status of their service.”
