Firefighters, baggage handlers, and security staff are among those taking part in the industrial action.
The Unite union urged bosses to “get around the table and negotiate a fair deal” with workers – or face the consequences.
Industrial action is due to take place between 07:00 on Friday, May 25th and 06:30 on Wednesday, May 30th.
The union said the strike ballot was in response to the company’s “paltry pay offer, despite sky-high pay increases for the bosses and record passenger numbers”.
The airport previously said it had already made a revised offer in line with inflation and qualifying employees would receive a bonus of about £5,000 from its profit share scheme.
A spokesperson for London Luton Airport said: “We are disappointed that Unite members have chosen this course of action and recognise the uncertainty this news will cause for our passengers.
“We are working with the 73 per cent of staff who did not vote to strike, to mitigate the impact of any action.
“We also remain committed to continuing discussions with Unite in the interim before any such action can take place.
Luton Airport said it would will keep passengers regularly updated via its website.
The airport added its staff receive a remuneration package in-line with the rest of the market, including a competitive salary, private health insurance and a generous pension scheme.
