Going on a vacation seems like a great idea but traveling internationally is not completely fuss-free either. You will have to go through a couple of metal detectors, take your laptop and iPad out of your well-packed bag, take off your shoes (sometimes!), talk to a bunch of law-enforcing people, remember where you stuff your phone and wallet (and passport!) while still keeping the time to catch your flight. When you finally you get through it all and sashay down to the gate printed on your boarding pass minutes before boarding, your greatest nightmare may then hit you there and then - gate change. Here's a solution and I'm giving out 5 FREE Flight Alerts below so read on to find out how to win them!
