I'm guessing it's part of an integrated suite for their reservation system.
There's no reason they couldn't use POSIX compliant OS's or others, but Windows tends to make big inroads into corporate and they try and sell it as a low TCO when often it isn't.
We'll never really know I guess.
But there's no reason to re-invent the wheel. It's just as easy to take a core OS (be it Windows Server/*nix/BSD etc) and build what you need on top of it. Different solutions will suit different situations, but sometimes the wrong solution is implemented.
I've seen ATM's (I believe it was ANZ) crashed out at the windows screen. As others have said there is no need to build solutions from the base OS upwards.
To build your own system from the ground up you'd need
- The Base OS
- Drivers for all hardware
- A set of libraries for standard protocols
- IT Support (keep in mind you can't easily replace technical people for a completely custom system, thus existing people can start naming their price)
and then you may not even end up with something as stable as had you simply used a pre-existing system and built on top of that. Furthermore just because it's custom, doesn't make it more secure.

Cool, cool. I just wondered, as it’s a common site to see Windows giving an error screen on a device, but not to my knowledge have I seen other devices displaying another OS error, though then maybe I have but their error isn’t obvious. So I guess they’re an easy target, but thanks for the insights
