There has never been a better time to comparison shop for flights… because there has never been such an abundance of online travel search choices. Aggregators and Online Travel Agents (OTAs) such as Expedia, Skyscanner, Google Flights, and Kayak are just a few sites that can be checked to comparison shop for travel choices. Of these and others, you likely have favorites with travel search features you like. The reality is that in most cases, only a few may have ‘best’ options.

If you’re serious about finding the best options, it’s worth checking at least 3 aggregators or OTAs. Once you find routes that you like, search that airline’s site directly for recently added specials.  Also remember, there are sites like Southwest Air, that rarely show up on aggregator sites so it’s a good idea to add them to your regular airline checklist.

To help decide which travel sites you like best, here are a few with a quick-list of their useful or unique travel search features.
