As with my most recent posting on LHR I have to speak as I find and MIA on 2 April was a good experience. It is a long walk from the gate (BA) to immigration but ours was the only flight and we were processed in five minutes. Officials were marshalling excess visitors into residents booths and keeping the whole thing moving. Surroundings were light and airy and fairly clean. They have introduced the ten digit scan but it was not unduly time consuming. My immigration official was pleasant. Baggage was fairly swift. The high outside temperatures seep into many parts of the building. The Alamo shuttle staff were very friendly. Alamo itself was a bit of a let down as there was a problem with our reservation and no easy access to baggage carts.
