Workers who assist disabled passengers and others in need of help are planning to hold 48-hour walkouts on November 20, 26 and December 21.
Gatwick has been at the centre of recent debate with chiefs looking at using their reserve runway to accommodate more flights. Tunbridge Wells lies within the flightpath to the West Sussex airport.
Unite has said the workers are at loggerheads with the airport’s management over a proposed £1 per hour pay increase.
A spokesman for Gatwick Airport said: “We encourage both sides to continue discussions.
“The welfare of our passengers remains our top priority, however, and we remain confident that services at the airport will not be disrupted as Wilson James has a range of mitigation measures ready to put into place.”
