We have been there and done the wondering around airports looking for our next gate on connecting flights, we have found in recent years the availability of online information helps make it easier to plan ahead and take away any uncertainty and allow you to enjoy the experience and have time to browse or stop for a meal. Therefore, whenever we travel, we make a point of checking out any airport that we will pass through. Whether just using the information to know the size of the airport area, know where to head for gate changes or while on a stopover what shops or services are available, I always check it out ahead of time and download a copy of the airport map to bring with us.
You usually do not know your departure and arrival gates until close to the time you depart or it can change. I will have a printed out copy of the map with me as well as a link I can access from my tablet or phone. I use the time while waiting to board to review the new airport to be sure I know where we will enter and where we have to go next. There are a lot of very large airports where you may come in on one end of the terminal and have to go to an entirely different end to connect with your next flight. Having this information saves time when you get there.
Whenever we travel and have to be at another gate to depart we always go to the new gate as soon as we get there just to be sure we know where it is and then we will explore the airport or get something to eat once we are confident where we will have to go and how long it will take us to get there.
In the past I would look up each airport individually to get the information that I wanted but I have stumbled upon a great website which provides links to most world airports.
So on your next plane trip try it out and have a great trip.
