The deck is good but you can also park on East Lake Blvd for great views. It runs parallel to 6/24 and is close enough and elevated over the runway to allow great views. The city even puts trash cans along the fence to accomodate this - very different than most places these days.
The easiest way to get to this area is to get off I-20/59 at Tallapoosa St and go north. East Lake Blvd will be the first right turn(Cowboy's is on your left). If you get to the guard bases you've gone too far.
Also, you have to eat lunch at VJ
's on the runway. Great lunch! Their old location is literally under the planned runway extension so they had to move recently. They are on East Lake Blvd. on the side opposite 6/24.
You'll mainly see 737, various flavors of Rj, and DC-9/MD whatevers with a few 757s and the odd 767 for airliners. Military is mostly KC
-47, and UH-60. Fedex/UPS fly a variety of A300/310, 727, and 767. Charters and private can be literally anything and everything. I've seen everything from Taylorcraft and Cubs up to AN
-124 and 747.
Another interesting local airport is at Gadsden. There is a company there that imports various Eastern block fighters for resale, training, etc.
Shoot me a message if you have any questions.
p.s. Forget seeing anything on 18/36 for the next few weeks as it is closed for construction
