It is not uncommon to see AHL (and CAL) showing up in commercial imports. Once you look at a map it's pretty easy to see why - the rivers near the ocean, the fish exporters and the airport are all near the same place. This is why members of the coastal species such as AUS, AHL, CAL and so on show up much more so than, say, EXI or anything far away from major cities and therefore airports.
