Some of the signage in the South Concourse of T3 still reflects a large number of non-existent gates (e.g. 1-15). As noted earlier, Sky Harbor has plans to renovate/rebuild the South Concourse of T3 for UA (which would result in the closing of T2). AS is supposed to be moving to T3 (North Concourse) shortly.
