This has been handy for me lately, as every flight I book is delayed or has some type of problem...For travellers who are REALLY on a budget and are looking for a way to skim a few bucks off their travel expenses, why not consider sleeping in an airport? Many airports are actually better than local lodging. And to top it off – IT’S FREE! Your friends and family may look at you funny when you return with your airport stories, but that’s only part of the fun. So now, sit back….get out your travel itinerary and plan which airports you’re going to sleep in (or avoid altogether) during your next trip. Link.
