British Airways workers at the airport have decided to go on strike.
The check-in staff and ground crew of the two unions supported the industrial action.
When demand from travellers is expected to return to pre-pandemic levels, 700 workers are going to go on strike.
The unions said there was a 10% pay cut imposed during the peak of the Pandemic.
It is thought that if the strikes go ahead, British Airways will cover staff, including managers.
There would be disruptions for passengers, especially at terminal five, which would lead to the cancellation of many flights.
The check-in staff at British Airways haven't had a bonus in a long time.
Staff at British Airways were offered a 10% payment for this year, but it was turned down.
The business lost more than $4 billion during the Pandemic.
"We remain committed to talks with our trade unions about their concerns and we hope that together we can find a way to reach an agreement in the best interests of our people and our customers."
After British Airways' staff shortages and IT failures almost brought the airport to a standstill, staff wereverbally and physically abused by angry passengers.
They had their pay slashed when they were hired by BA. They want the money back.
If the strikes go ahead, the summer of travel would be chaotic.
In the last few weeks, thousands of passengers have been affected by airport disruptions.
Hundreds of flights across the UK were canceled during the week of the Platinum Jubilee and school half-term holidays, raising concerns of further travel troubles during the summer.
The aviation industry is struggling to cope with increased demand for overseas travel due to a lack of staff.
The annual passenger forecast has once again been increased by the airport.
According to the guidance it gave in December, the airport expects more than 50 million passengers to pass through its terminals.
