We know, we know -- a connecting flight is the last thing you want to consider when you're booking your air travel. Connecting flights don't have to be terrible, though. When you're looking for flights, the best way to save can sometimes be to consider a connecting flight. Look for connections that make sense. You want to have enough time to get to your gate if your flight is running behind, but also not so much time that you'll be pulling your hair out. If you can find a flight within that sweet spot, and an option that'll save you $100 or more, it might not be the worst idea in the world.
