Union officials have postponed strikes planned at Heathrow later this month to consider a new pay offer.
Some 4,000 members of the union Unite were due to walk out on August 23 and 24, causing chaos for families during the summer holidays.
However, the industrial action by workers has been postponed to give the union time to ballot members on the new offer.
The ballot will close on Monday, September 2.
Heathrow said it had ‘put an additional £2.5 million on the table’, offering staff a pay rise of 7.8% over two years.
Earlier this month, airlines cancelled 177 flights in preparation for strikes by security, airside operations and passenger services personnel at the airport’s five terminals, which had been planned for August 4 and 5.
The strike action was postponed just hours before the walk-out to allow talks at the conciliation service ACAS.
