The internet booking engine Expedia recently released a comprehensive data review of air travel trends for 2015, They came up with a pretty good list for travelers looking to save time, money and aggravation in booking their next trip.

Book early to save big. Our analysis of industry data indicates that the earlier you book for both domestic and interna- tional travel, the bigger your per-ticket savings could be.

Be sure to check fares on Tuesday. Expedia data indicates that when buying an air ticket more than 21 days before the date of departure, Tuesday still offers travelers the greatest likelihood of finding a good deal.

Consider premium cabins. Over the last few years, the fare gap between ticket prices for premium and economy classes has dropped precipitously. This means tickets for the best seats on the airplane may be more attainable than you might think. (At the very least, check it out.)

Book as a package. Just like cable and internet service are cheaper when consumers purchase them together, travel is cheaper when air tickets are purchased as part of a vacation package that includes a hotel and other travel services (such as a rental car and/or activities).

The takeaways from Expedia’s report seem to be often overlooked, but these seemed to make sense.  The full report from Expedia can be found here. Does anyone have a killer flight booking trick they’re willing to share?
