I can echo what Zemmervolt has said, and add a caveat based on personal experience. If possible get one case that will hold everything - camera, lenses, laptop and accessories. Airport security requires laptops to be removed from the case - then shoes, jacket, belt buckle, watch, etc., etc. all go through the scanner. Then it is chaos trying to get it all back together again with very little room to do it and lots of confusion,.
I had separate cases last summer and when all was said and done, I walked off and left my camera case at the TSA scanner exit. Long story short - I got it back in September, but it was not fun.
You can get some decent pictures from an aircraft window - they are a type of plastic/plexiglas, and not optical, but if you are at a low enough altitude, you can get some neat pics. Once you get in a jet over 30,000 feet, and there is no sunset - unless you like the aircraft wing or clouds, there's not much to see.
Here are a couple of shots I got after taking off from Oakland airport and the plane headed West by the heart of San Francisco then over the Golden Gate.
