Airline's IT is too clever

Yes I know, clever airline IT is an oxymoron.  And to prove the point, it seems bmi has it’s website restrict which country-specific version(s) you can access based on your IP address.

It may have seemed a good idea to some at bmi – stop clever UK-based people from booking sales ex-Europe or ex-USA.  But it doesn’t seem to be well thought through.  Perhaps they haven’t heard of multi-nationals having non-local IP addresses?
