Honestly, no, no, no. Not all layovers are created equal.
Yes, sometimes if you plan it right, it's possible to add on a quick tour of another city for free.
Except there's one problem. Some of the most accommodating layovers are overnight. The overnight layover is rife with problems-yes, it means an extra eight hours in a foreign city, but though it also means scoping out a city when everyone is sleeping and all the stores are closed.
Exactly what you thought of when scheduling it, right?
It's better to schedule a six-hour layover in Copenhagen starting at 11 a.m. than a 14-hour layover that starts at 7 p.m. (By the way, that last layover means the flight would be out around 9 a.m., just enough time to see nothing.)
Unless you're a serious night owl that loves interacting with absolutely no one, the overnight layover is the most useless way to see a city.
To make matters worse, it is also expensive, because it also means an additional hotel night, unless sleeping in the airport is your thing.
(Let's face it: It also means that additional hotel night is usually right next to the airport, lest you miss your connecting flight, practically defeating the point of seeing anything outside of it.)
