Wanted to share some info for anyone in the New Orleans area. After talking to Bryce ("KMSY", who runs the local feed), searching a little on the Web, and doing some good ole' ground-pounding, I staked out some great spotting points around the airport. Unfortunately, they are only useful for RWY 19 and 01. As far as I can tell, if you wanted to spot RWY 10, which they use A LOT, you would have to fend off the snakes in the swamp and/or climb a cypress tree.
Here's a map for reference:
Anyway, for RWY 19, you can take Veterans Hwy and turn onto Bainbridge. Head south, then make a U-turn around the canal. Then you can head down 26th St and end up right near where the taxiway turns onto RWY 19. There's also an "adult bookstore" on the street for those lonely low-traffic times, if you're into that sort of thing.
RWY 01 is much more fun. You can either head down River Rd. to the intersection with Williams Blvd. There is a parking lot there with a trail that leads up to the bike path on the levee. Head west (upriver) on the bike path until you see the high-tension power line towers on your left get shorter. This is a fun, quiet place to sit on the levee and spot. Also, you can park in the Cell Phone Lot (look for the big brown sign) on Airline Hwy. This is a lot that the airport management designated for people to park and wait for their family/friends to call them once their plane has landed. Ostensibly to ease the congestion in the airport drive-thru, it seems like a good idea, but I only ever see one or two cars in it. But if you park on the east side, the planes pass nearly right over you, and the lot has a security guard if you're worried about going there at night. Also the road right next to the lot (George St.) would be good, but there is some traffic on it, and not much of a shoulder for parking.
I don't know if there is anyone else here that is from the New Orleans area. If there is, speak up. We may not have Virgin 747s landing, but its still a pretty cool airport with a good amount of traffic. I think I'm going to hint to my girlfriend for a handheld scanner so I can listen while I'm out there.
"Mad props" go out to Bryce for his feed (which seems to NEVER be down) and for the extremely helpful map he created with frequencies and landmarks/waypoints/navaids.
