A programme is underway to replace the current hold baggage screening system with an advanced x-ray system, which will more than double the hourly baggage processing capacity.
Other major improvements include developing a drop off car park, which will be free for 30 minutes and connected with a covered walkway to the terminal entrance. Existing car parks will also be upgraded, and a new surface car park is planned.
An ambitious programme to double the number of self-service bag drop kiosks will be installed as well as digital check-in branding to improve operational efficiency and aid passengers.
The ATC Surface Movement Radar will be upgraded to enable critical safety enhancements and operational capacity.
Paul Kehoe, the Airport’s chief executive, said: "We have seen enormous growth at Birmingham Airport over the last few years and we are currently welcoming 11m passengers a year through our terminal.
"We’re therefore making this investment to enhance operational efficiency and improve the passenger journey in time for the summer ‘17 season, when we’ll welcome 15 new routes with Jet2 and anticipate in excess of 12m passengers over the next year.
"Looking more long-term, Birmingham Airport is in a unique position, as in 10 years’ time it will become the UK’s only HS2 connected airport, growing the catchment into London with high-speed trains and serving Birmingham from the capital in circa 30 minutes.
"We’re therefore working on our master plan to look at options which maximise the benefits of HS2 for Birmingham, the wider region, airlines and passengers.
"This will allow us to scope out how we can create a truly integrated transport network that can take the pressure off the overheated London system and transform our facility from a 25 million potential passenger site to 60m plus in the future."
