If the judgment was as a first-time visitor to an airport, then a large number of airports would fall in this category in the UK and US - LHR, IAD, BOS, DFW, MIA, etc. A frequent traveler from IAD arriving at LHR, the first few times would make exactly the opposite conclusion as this FT article.

Once you get used to these airports, "it works" at all airports but some continue to be difficult to use because of the design and the crowding. These include IAD, DFW and to a certain extent LHR.
