If you're trying to get some PC-related work done on a long-distance flight, it can be a real nuisance when the person in front tries to maximally recline their seat. Blogger Angus Logan came up with a slightly tongue-in-cheek but workable suggestion: brace the seat in front of you using a bottle to reduce the possible reclining angle. As he points out, the bottle in question needs to have straight sides, and there's no guarantee an officious airline staffer won't tell you to move said bottle, but if you have to get some work done, it's presumably worth a try. (Make sure the bottle's empty when you clear security to avoid liquids dramas.) Check out Logan's post for other suggestions on how to deal with the reclining challenge.
