Stay alert and organized
When traveling, there are many things to keep track of, especially dates and times. You wouldn’t want to pay $60 at the airport for forgetting to do the online check-in, as I did in Santiago de Compostela. Always have your checklist in mind.
An excellent way to prevent this from happening is to download apps that keep track of all your travel information. Some apps allow you to create to-do lists, and others keep an eye on your flights and warn you of departure times.
