A gate is the part of an airport which provides a waiting area for travellers before boarding their flights.
Flight gates provide an opportunity to advertise to specific sets of audiences flying to set areas of the world, by targeting the walkways in specific parts of an airport. Additionally, they allow for reinforced advertising to passengers that are waiting at specific gates for their flights. This means any one advert is likely to remain in their mind for a longer period, following longer exposure.
When at the gates and the departure lounge, travellers experience a high state of arousal, meaning this as an opportune moment for short, visual, impactful messages and advertising.
Gates can be split differently in separate airports, but generally there exists a separation between international and domestic flights. Further, gates may be split into airline, geographical area or country groups. In this way, advertising can be targeted to a specific footfall if placed at the gate, and a more general one if placed in popular walkways.
