Thanks for all your comments guys & gals, the search continues; although we kind of gave up after landing in Cape Town if im honest (shameful i know). We live with the thought that he's 'pigggy-backed' a ride with some world weary traveller for company and is now sat on the beach in the Seychelles.
We're off to Dubai on Monday and he's not really welcome there anyway!

It has to be said the BA staff at the satellite gate were brilliant as were the Galleries lounge staff when alerted to Kevins disappearance on the night. Sadly, the search was 'ham'pered by our flight leaving!

we may create a memorial wall in the Galleries lounge so keep your eye out next time you're travelling through!!
