I love coding on airplanes. Last time I was on a plane, I was writing some web-something that I can't fully remember anymore, but what I do remember is that I needed MarkDown, but didn't have lib or the api docs. Since Google and Github weren't available, I fired up spotlight, found a random js file in some old folder, and had to use Chrome inspector to navigate the api, and man was it rewarding!<p>I love it for the challenge. Coding without the internet is not something I do often, but for some reason, at 30,000 feet it's simply therapeutic.
The lack of distractions is appealing, but I'm only 5'6" and I find airplanes to be extremely uncomfortable. I can only imagine how bad it is for someone that's average height or taller. I've done work on a plane, but it isn't really an experience that I long to duplicate.
Yep, I find coding on planes to be pretty productive too, if only for the fact that it's not like you have anything better to do. The only hard part is looking stuff up, like APIs. I find airplanes really useful for code reviews though. I often end up with less code after a flight than before.
