Wonders, on the Delta website you should be able to find layouts of the planes. It's under a heading along the lines of "travel tools" along the top of the home page.
My 2 cents about convertors/adaptors: a converter, which prevents your device from being fried by the higher current, works great for when you need to charge your phone, or your camera batteries. If you like to use a flat iron for your hair, or have some other "high drain" appliance, it will not work. It tones the juice down
too much. Having tested this on two trips now (and living with crazy curly hair in all the pictures!), I will be buying a dual voltage travel flatiron for next time.
As for adaptors, be sure to check the plugs on all the items you will bring. DH's laptop plug only had two prongs (like the other stuff we brought), so that was the adaptor I brought. It turned out that DD's laptop had a three-pronged plug, so I couldn't charge it even though it is dual voltage.
Have a wonderful trip! Planning so much ahead of time can be great if you're able to relax and enjoy when you're there, knowing you've controled what you can control. Can't wait to hear all about it!
