Dnx will be responsible for producing partner-linked promotional work and marketing initiatives over the peak summer months, as well as creating data-driven programmes to help drive customer preference and revenue across its retail, catering and car-parking amenities.
The campaigns will begin to roll out towards the end of this month, and will continue throughout the summer.
Dnx will work closely on the account with Gatwick Airport's above-the-line agency, Naked Communications, and its media partner, Mindshare.
Both Naked and Mindshare were appointed to the business last month following a series of pitches.
Tim Wall, the retail director at Dnx, said: "It's great to be working with such a prestigious client at such a key time for them. We are confident that our campaigns can deliver some really tangible commercial results."
