On the flip side, don't wait until the last minute either. I had to get to boston this week last minute. Direct flight from philly to logan would have been nearly 700 bucks. I found a delta flight instead through detroit to manchester NH for $210. The connection sucked but it was better than driving. I know I could have flown direct for 2-300 bucks had I booked it just 2-3 weeks ago. So don't wait too long!
