Urban legends are shared so often that we take them as fact — and they usually sound reasonable enough so that we don’t question them. Waiting to swim after you eat so you don’t drown? Sure, sounds right. Swallowed gum stays in your stomach for seven years? We’re no gastroenterologists.

Myths like these have seeped into our travel planning, too. Is there really a cheapest day to book a flight? Can you drink tap water abroad? But just because you hear something over and over again doesn’t make it true. We decided to dig into some of the most common travel myths and find out whether they’re actually accurate.
