Has anyone bought and used one of these?

A hard case, ostensibly for a folding bike, I was thinking of getting one for my S&S coupling bike to take on holiday, rather than lumping around the softbag which is a little unwieldy, especially with two children to control.

Has anyone used one of these before? I know the dimensions are not within limits set for ordinary check in baggage, but I will probably be flying BA and not some horrid american or budget airline where they do you over.

Thoughts?

Thanks in advance
