DO be flexible

• Fly on Tuesdays, Wednesdays and Saturdays -- historically the cheapest days to fly

DON'T be picky

• Non-stops can be more expensive than connecting flights • Flights to regional airports are usually more expensive than flights to big-city hubs • Compare routes and nearby airports to find the cheapest flights

DO use a carry-on

• Avoid expensive checked-bag fees on most airlines • Carry-on bags do not get lost • No waiting at the baggage carousel
