What happened to Heathrow? When I lived in London, I seem to recall quite liking this airport. Terminal 3 looked in shoddier condition than the Nairobi airport, which was one of the more unpleasant airports I've flown through in recent memory.
I have a longer story to post later, but for now, I'll leave you with this… to get from Terminal 3 to Terminal 4, because the Heathrow Express was out of service, I had to take the Tube from T1,2,3 to Hatton Cross then back to T4. It only took me 90 minutes to change Terminals. No big deal.
