If you've ever traveled on a commercial jet, you probably know to avoid picking the middle seat in a row of three. If you purchase a last-minute ticket or you didn't select a seat before check-in, you might not have any other choice but to sit between two strangers on a long transcontinental flight, but assuming you do have your pick of where to sit, it's worth spending a few minutes to make sure you're getting the most bang for your buck.
Have you ever experienced this scenario? You are nearly finished with the online booking for your next flight when the airline's reservation system prompts you to select a seat. You are stumped. Which seat do you pick? How do you know if 8A is better than 14C? What if you end up in one of those seats that don't recline?
