Is there a way to work on a MacBook Pro on >10 hour flights?
Whenever I am on a long flight, I try to be as efficient as possible in laptop usage. Everything that I don't need is switched off, from WiFi and Bluetooth to any other unneeded app.
I mainly need to write, so this way I can manage up to 5 hours. On my previous Mac, I simply had an additional battery packed, which would allow me twice the amount of working time. Unfortunately, Apple decided to make the battery an integral part of the laptop.
On my 11 hour flight last week, there was however this guy who was working all the time on his laptop and I saw him coding and compiling all the time. I intended to ask him how he managed to do that without external power available while deplaning, but I simply forgot :(.
My question is how can I work on a MacBook Pro longer than 5-6 hours when on a long flight with no external power available?
Best Answer
The most obvious solution is to procure an extra, external battery.

Security. Most people opt to carry their laptops onboard the plane so they can use them in transit. If you carry on your MacBook, you'll need to take it out of its case and put it into a bin when it goes through the scanners at airport security.Which MacBook Pro is not allowed on planes?

Answer 2
Apple claims the 2013 version of MacBook Air has battery that can last up to 12 hours. MacBook Air-Wikipedia
A test performed by The Verge, for example, found Apple's claim to be accurate, with the laptop running for 13 hours and 29 minutes while "[cycling] through a series of websites and images at 65 percent brightness." Theverge.com MacBook Air review
Of course, if this guy is coding and testing a CPU-intensive program (such as a 3D game), that will use up the battery faster. But, for "normal" programming, it should be comparable to the test The Verge has performed.
Answer 3
One of the big consumers of electricity is powering the screen. Lower the brightness to the lowest you can possibly tolerate. The other big consumer of the electricity is the CPU. While you can't avoid using the CPU, you can reduce the strain on it by shutting down any unnecessary programs in the background such as iTunes.
You also need to ask yourself if it's reasonable to expect 10+ hours of battery power if your laptop is anything less than new. Battery lifetime can be shortened drastically after a couple years of use. From personal experience every laptop I have owned has gone down in battery life by 50% after a year. I've improved this number a bit with better battery charging habits, but the decline is inevitable.
But those are more technical tips. As far as travel goes, there are airlines that have outlets at every seat. The only one that I have personally been on to offer outlets and powered USB ports is Air Canada. If writing during a long flight is this important, you should do a little homework to find an airline with power outlets. I know that Virgin Airlines also has outlets and I'm sure with a little searching you will find many many more.
Answer 4
The latest version of OS X (Mavericks) is available as a free upgrade, and reports are that it lives up to its promise of conserving battery life. The Mavericks battery monitor also tells you which applications are consuming the most power: you may find find that some seemingly-innocuous background apps are consuming much more power than you expect, and can be safely deactivated.
Other than that, just follow the usual advice. Dim the screen, turn off the wireless, close the laptop when not in use, turn off Flash animations, and so on.
And if you have money to burn, treat yourself tothe latest model Macbook Air. It will easily see you through a 10 hour flight if you're not maxing out the CPU.
