Between long layovers and delayed flights, sleeping in airports might not seem like a bad idea. But before you try it, here’s what you need to know.

If you’re looking for a quick nap, the transit lounges in most airports can do in a pinch.

But some airports, like those in Vancouver, Dubai and Istanbul, do offer sleeping pods or by-the-hour airport hotels for naps.

If you do get stranded overnight in an airport due to flight delays, make sure to ask your airline for a hotel or sleeping pod voucher.

If a hotel or sleeping pod isn’t available, visit The Budget Traveller’s Guide to Sleepinginairports.net.
