New regulations require airlines to post the full price of airfare, taxes included. The changes are meant to give consumers a more accurate idea of what the full costs of their flights will be, but they don’t always tell the whole story.

U.S. News & World Report suggests researching airlines’ fee policies in advance to get a read on the hidden charges that lurk. Checked baggage, in-flight WiFi, meals and other add-ons could add up. Check out this Kayak chart to compare the various fees and policies of each airline.

Booking flights on the sticker price alone may lead you astray, so pricing out the full cost of your flight and the amenities you’ll need will help you compare apples to apples.
