Sjy Harbor
While visiting we had excellent results with the 396 by setting up a system for the PRWIN fill-in site located at the airport:

If just want to hear airport stuff just program the single sky harbor site listed.
You'll find a talk group list located there, though I'd suggest actually working the site in open / search mode, as we found a few talkgroups which weren't listed and you might be able to figure out what they are. It's a really nice airport.
The ATC stuff was also quite interesting:

You also might try searching 128.825 to 132.000, AM mode, 25 KHz steps for the airline stuff, as well as regular business bands. It's a busy place.
Happy Scanning! - Ted
