Effort: MinimalCost: Free
Even for seasoned travelers, long plane trips are a bear. The simple key to toughing one out is to get a good seat. is a free service that provides you with a detailed, color-coded layout of virtually any plane to help you find the seat with the best legroom and most convenient nearby power outlets while avoiding nonreclining seats stuck right next to the john.
Bonus tip: Not that we're advocating messing with your airline seat (or with other passengers), but if you're desperate to prevent the person in front from reclining into your precious space, try wedging a water bottle between your open tray and the seat in front of you.
