The RMT union announced the walkouts in a dispute with the firms over plans to remove guards from trains, which would become driver-only-operated (DOO).
Union officials, who confirmed the 24-hour strike on 13 March, say the move will make trains potentially dangerous.
There were 55 laser pen attacks on aircraft at Gatwick last year, according to the Civil Aviation Authority.
The West Sussex airport is in the top ten most targeted in the UK.
Earlier this month, the Department for Transport announced plans to introduce new legislation meaning people who shine lasers at pilots could be jailed or face hefty fines.

These squirrel monkeys at Drusillas have had a Shrove Tuesday treat after pancakes were added to their lunch menu and served up in a frying pan.
But if you're looking for tips on the perfect pancake, I'm not sure it's a recipe to try at home...
They were made from a mix of porridge oats, baby rice, baby formula and whey powder, bound together with sunflower oil and sweet potato... all the foods that keep the monkeys fit and healthy.
