1. Always have a backup plan This is the most important tip for anyone who voluntarily sleeps in airports. Some airport officials are not totally supportive of the airport sleeping idea. Although you won’t be kicked out of a large majority of the airports listed on this site, you will be asked why you are there, why you are not in a hotel like a normal person and they will ask for proof that you are flying out the next day. So BE PREPARED to answer those questions and present your outbound airline ticket! They seem to not appreciate us using the airport as our personal hotels — go figure!?!? Our airport guides provide you with information such as the availability of airport lounges, WiFi, transit hotels, 24-hour food options, showers and much more at over 800 airports around the world. And you can also read airport reviews from travellers just like you.
