Having flown into LHR T2 last week, something really needs to be done about the queues in immigration. Took me 2.5 hrs as a non-resident colonial to get through. Add half way through the lineup I came across a sign telling me that the new faster immigration system had arrived. Strewth, I'd hate to see the old one.
Forget the runway. Fix the infrastructure that is there! Surely if tourists bring in billions to the economy then it is the country's interest to encourage them back again.
