Around 700 members of Heathrow airport workers will strike between November 18 and November 21, potentially disrupting travel plans for football fans planning to fly to the World Cup in Qatar.
Unite said the walkout will particularly hit Qatar Airways, which has laid on an additional 10 flights a week during the World Cup.
The tournament kicks off on November 20, with England starting their campaign the next day.
The strikes are the latest to hit the UK, where train workers, dockers, postal staff and the legal profession have all announced walkouts amid a cost-of-living crisis fuelled by rampant inflation.
