BA check-in staff at Heathrow are balloting for a July strike.
Unite, the union, said that the workers had a 10% pay cut imposed on them during the coronavirus pandemic but bosses have refused to reverse this, despite restoring their own pay to pre-pandemic levels.
The industrial action ballot, covering about 500 staff, will open on 7 June and close on 27 June.
If workers approve strike action, it is expected to take place in July - the peak month for summer travel.
