Even if they help you or not, here are a few tips for when your in one of the big airports.
1. Be prepared for huge crowds ( it may be due to travel season or weather delays, you may be traveling during the heavy seasons)
2. Be prepared for delays ( if your flight comes in late, don't worry, just stay optimistic and hope you get to your gate in time)
3. Cardio and Focus ( if you arrive late and your next flight is located at a gate far away, be prepared to run as fast as you can to get there. If it's also crowded, then you better have some good attention as you navigate around other travelers)
4. Pack modestly ( if your bringing a travel bag, make sure to pack a right amount. You never know when you have to run through the airport with your bag weighing down on you. As for smaller carry on luggage, wish yourself luck on carrying it around.
5. Go for the movers ( the moving sidewalks an escalators do help with moving along, they even offer a good place to rest for a sec)
6. Don't get mad ( if you get to your gate and its to late to board, don't get upset. Keep a good smile on and try to work out a solution to get on a new flight, you may be supprised on what you may get from the flight workers)
And last but not least......
7. Enjoy the little things (if your stuck waiting for your next flight, then enjoy what the airport your in has to offer. Eat at a resturant, shop around a bit, get a book to read, surf around the Internet on your phone or moble device. Take your time to enjoy yourself and relax for a bit)
And those are my tips for when your at a large airport, I hope it helps a little~
