1. The lowest listed fares are usually on Tuesdays and Wednesdays.
2. Use Expedia, Orbitz and other travel sites to see available fares, but make sure to double check the airline site. Often I can save $5-10 on service fees, and they have more time options.
3. Figure out what you will be paying to check baggage, for the emergency exit row, etc. Many airlines have extra fees these days. I love Southwest because they don't have baggage fees . I recently booked a trip on a different airline because the fare listed was cheaper. After getting to the airport and paying over $100 (each way) for baggage fees, it would have been cheaper for me to fly Southwest.
