Railgun,
I read your post with glee and wonder if your only form of transport is british rail.
I have been to 63 countries on my travels (including Nigeria,Ivoiry Coast,Ghana,India,Kenya)and believe me Washinton and Manchester comes out pretty well. You have obviously not flown through LHR recently. I fly through MAN quite frequently and must admit its not the best airport in the world but at least i find my baggage on carolsel nbr 5 10 minutes after ive got to baggage reclaim and not 3 days or weeks after unlike LHR. I can put up with leaking roofs and inoperative escalators but get really pissed off with the lack of luggage at the end of my journey which is normally the case at LHR.
Where does LHR come into your worst airports in the world table.
