Ronaldsway Airport on the Isle of Man will receive an update to its security area after Easter.
It follows complaints made by passengers waiting to go through the system over the past few months, with an increase in queues.
The entrance to the Central Security Area is to be relocated and will continue to include a separate dedicated route for passengers requesting assistance, such as those with reduced mobility or medical needs, or those attending hospital appointments in the UK.
Automatic boarding card readers will be installed, and the security area remodelled, increasing in size by 160 square metres.
An automatic tray return system integrated with the X-ray equipment will enable several passengers to put their belongings on to the X-ray queue at the same time.
The Department of Infrastructure's contractor has been asked to recruit the additional staff needed to allow the second X-ray line to be operated at peak times.
More information will be provided shortly after Easter, following final confirmation of equipment delivery times and a programme of works.
