Saturday Morning T5 at LAX, at 10:35am first PE PAX off VA1 after waiting for Business to disembark, passed about 20 with a long meandering but brisk walk - along then up a level, along some more and more then down two levels then along again to a small immigration hall.
Was about 30th in line for Visitors/Foreigners queue, which had 5 booths processing. The front 15 were Chinese from another flight, remainder VA1 Business PAX (a surprising number of VA1 PAX appeared to be US citizens and basically went straight through).
Initially the line moved slowly while the Chinese completed processing, but after about 15 minutes once the VA1 PAX started processing it sped up dramatically; in the end I was out after 20 minutes and was having a shower in the T4 F/L by about 11:15am.
That T5 hall is small - I passed many snaking metres of movable tape barriers in the corridors approaching the immigration hall - obviously it was not peak when I came through.
