Standardized (and shrinking) airline seats have made it difficult for people of all shapes and sizes to fit into an occupied space with set dimensions, because not everybody can fit comfortably. However, not all airline seats are created equal.

Google Flights is one of the most powerful tools for finding the best airline deals and routing. It can save you a ton of time relative to searching around on the websites of individual airlines, and it works well for both domestic and foreign airlines. It even has features built in to help you find great airfares even if you don’t know exactly where you want to go. More on that below. But first, what it is and how it works.

When we are talking about air travel, positioning can mean one of two things.

In the aviation industry, a positioning flight occurs when an airline needs to send a plane to another place for conducting a flight. It can be a passenger or cargo plane that ended one flight in one airport, but must start another commercial flight in a different airport. In the past, these flight used to be conducted without passengers, but that has changed. There is a whole underground science of spotting these flights because many people believe airlines sell discounted tickets for them. But for award flights, it’s different.
