The US is a large country and the climate varies by region and time of year. It experiences four seasons, but some areas of the country see a more drastic change between seasons than others. The Pacific Northwest has cool summers and mild winters, while just to the south, the West Coast is sunny and pleasant all year long. The Midwest sees a bigger change between seasons, with strong summers and winters and frequent tornadoes and thunderstorms. The East Coast fluctuates and many people head down to Florida to get the warmest winters on that side of the country. Traveling in the off-season can save you a lot of money.

Use skyscanner.net. This neat website searches all airlines, big and small, and allows you to look for the cheapest rates out of your local, rather than getting bogged down with specifics.

If you're flying somewhere that involves a transfer, say from Canada to Australia which typically involves Canada to LA, then LA to Australia, consider that it may be cheaper to book these two legs separately on your own by adding another destination to your trip. It should go without saying that in doing this, you should not book tight layovers. I repeat: do not book layovers that are hours apart! This approach is for those who want to create an additional destination of a few days or more, before catching their next flight. The one exception is when booking with Kiwi.com, who offer their own guarantee on making connecting flights even when not with the same partner airlines.
Why it's awesome: Even though Virgin America is no longer the best low-cost airline in North America, it remains one of most beloved carriers in the skies. The San Francisco-based boutique carrier offers the style and high-quality service expected from a Virgin-branded company, but with the competitive prices of a low-cost carrier. In 2016, the company was sold to Alaska Airlines for $2.6 billion. The brand is expected to disappear by 2019.
