DO search for flights midweek.

 

 

Airlines tend to launch their sales on Tuesdays and end them on Thursdays, so don't limit your searches to the weekends. Advertised fare sales generally target the next two or three months of travel and have 14- to 21-day advance purchase requirements.

 

 

 

 

DO search for two one-way fares, even on different airlines.
 

While some airlines charge extra for a one-way fare, it can pay to compare. Just make sure to triple-check the dates, times and cities so you don't book two tickets from, say, Seattle to LA. Not that this has happened to any of our Deal Experts.
 

 

DO know when to be loyal and when to compare.

 

Keep a loyal rewards membership with favorite airlines to rack up points when it makes sense. Sometimes, it's worth it to book a slightly more expensive ticket when it earns you points. Many airline credit cards offer generous sign-up bonuses that are enough for a free flight, not to mention perks like priority boarding, free checked luggage and more. But, to make an informed decision, it pays to compare all available fares before booking.
