I recommend getting several magazines that you like as well as books and your mp3 player. If you’re concerned about weight, get magazines like Newsweek that have thin pages and really small fonts…but only if you like reading that stuff. Pick a few books that are easy reads and maybe one more technical book that you should read for work or something. For my next 6 hour flight, I may bring LSAT practice exams that I got free off Craigslist. I’m not planning on being a lawyer anytime soon, but I really enjoy logic puzzles, and each section is 35 minutes timed or something. That’ll be a fast way to pass the time. And the books are printed on paper similar to newsprint so not too heavy, and you won’t feel bad about leaving them at your destination because it’s really a one-time read thing. Crossword puzzles are fine, but it gets boring.
On one 12 hr flight, I ended up standing in the back of the plane talking to other people that couldn’t take sitting down any longer. A 6 hour flight is not that long. That’s how long it takes us to get from HI to the US mainland. You will survive.
