SITA CUSS 2 is changing the Common Use conversation. As the market leader with a footprint across 400+ airports, we give customers simple, actionable guidance they can align teams and timelines around. Each recommendation is built for the operational realities of live airport environments. That means clear messaging, clear milestones, and a clear route to what’s next.


SITA is here to help you make decisions early, reduce uncertainty, and move forward at the right pace – with a partner you can trust. 

CUSS 2 isn’t a minor update - it’s a fundamental architectural step-change. It's designed to meet modern application needs, stronger security expectations, and future innovation.

IATA has defined clear expectations for what CUSS 2 should deliver. It's a move to modern web technology, with security built in from 
day one. It also supports more devices and delivers updates faster. 
The goal is a standard that’s easier to evolve, easier to maintain, 
and better suited to modern passenger processing. And because 
it’s a genuine architectural shift, it needs to be delivered responsibly. SITA’s focus is making sure customers can move forward with confidence – aligned to IATA guidance and grounded in what works in the real-world. 

CUSS stays supported in production, and there’s no forced migration. So, you can keep today running, protect existing commitments, and plan what’s next on your terms.


Both applications can run side by side on the same hardware. 
That means no parallel environments and no duplicate kiosks just 
to move forward.


We’re also making adoption as smooth as possible. Clear documentation and IATA-aligned guidance – so when you decide to move, it’s gradual, predictable, and under your control.


For customers who want a faster starting point, SITA is developing 
a ready-to-use, brandable CUSS 2 check-in application as part of 
the journey.
