Work is underway to improve security facilities at Ronaldsway Airport.
The central search area will be made bigger providing more space for passengers to prepare for security.
Equipment aimed at improving the flow of passengers through the security process will also be installed – including new tray return equipment and a second security line.
It's hoped this will reduce queuing times and improve the passenger experience.
Infrastructure Minister Ray Harmer says: "Our vision is that passengers will have a smooth and speedy flow through the airport and I thank people for their patience while the changes are made.
"I hope that releasing this timeline of information will provide reassurance for passengers, and allow them to look forward to seeing the alterations take shape."
Director of Ports Ann Reynolds says: "Opening the second security line will, of course, make a significant difference and the recruitment process is under way to allow this to be manned permanently – a three-shift rota, seven days a week.
"Security and previous employment checks are clearly a fundamental part of this process and training can only take place once this has been taken care of."
Building work will stop throughout the TT fortnight.
