    I am Megan and I have been an air travel fan since my first flight at fifteen. Something clicked in me that day. I realized how much I enjoy the rhythm of airports, the feeling of taking off, and the way a simple trip can open your eyes to the world. I built Sole Vita Travel to share the kind of advice I wish I had when I started traveling. My trips taught me a lot about packing light, picking better seats, getting through security without stress, and finding small tricks that turn long travel days into smooth ones. I write in a simple style because travel is already complicated. My goal is to make flying feel clear and doable. I hope my guides help you enjoy your next trip a little more.
