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 try to fly at least one leg of your trip on a Tuesday, Wednesday or Saturday.

 

Because planes are least full on these days of the week, these flights usually have the lowest fares. Side perk: Getting through airports is usually a breeze.

 

 

 

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.
