Don’t be afraid of the little guy. It’s easy, and sometimes perceived as safer, to rely on large airlines as the sole means of air transportation.

Do a search of budget carriers in your area or destination and see if they also offer lower prices.

Search flights from nearby airports. This is a very simple and effective trick to find cheap flights. Sometimes flights from local airport to your destination can be quite expensive while, on the contrary, flights from nearby airports can be really cheap. For example, international flights from Seattle are quite cheap when compared to international flights from Vancouver and the distance between the two cities is only 234 km (about a two and half hour drive). So driving or taking a bus to the nearby airport is sometimes a good way to get to your destination cheaply.
Stopovers can range from a mere hour to even a full day (or more), so it's really up to you whether you would prefer paying less for your flights in exchange for doing some time at the connecting airport. The biggest issue is that time spent in airports eats into the "free" time you would otherwise enjoy at your final destination. If you do settle for a trip with a long layover, check into sights to see or activities to do near your layover airport. A 10-hour layover might provide the perfect opportunity to visit a famous landmark or explore a new city. To each, his own.
