The airport has completed an upgrade to the Tayto shelter in the Express Pick Up and Drop Off Area.
The installation forms part of Tayto's substantial brand presence at Belfast City Airport, which includes a 'Welcome Home' wall in the Arrivals Hall and branded vending machines throughout the terminal.
Sonia Armstrong, media sales manager at Belfast City Airport, said: "It is fantastic to recognise 15 years of partnership with Tayto, an instantly recognisable brand that truly embodies the spirit of Northern Ireland.
"The new eye-catching installation is designed to grab the attention of passengers travelling to and from the heart of Belfast and certainly leaves a lasting impression."
Elly Hunter, group marketing director at Tayto, added: "As an iconic Northern Irish brand, Tayto is excited to expand its presence at Belfast City Airport and build on its relationship, which has significantly grown throughout the last 15 years.
"We chose to advertise at Belfast City Airport because of the presence that it offered us as a brand, with lots of opportunity to make a statement, and the impact has been incredible."
