A mobile phone is a traveler’s most trusted resource. Before settling into your seat and setting your phone to “airplane mode,” there are many logistic hurdles to overcome.

GateGuru has created a mobile app that guides you through major airports. While other apps focus on booking a fight, this app is all about the airport experience.

The smartphone has revolutionized the way we travel. Having a few killer apps installed on your phone can help you find your way around the airport, get delay and gate change notifications, track flights in the air and know exactly when a flight has landed. Here are a few awesome apps that you should download and start using the next time you head for the airport.
