Here are Some Useful Tips for Beginner Travellers

Make copies of your important documents both online and on paper

Make sure your passport is up to date and won't expire soon

Purchase travel insurance, especially if your credit card already provides travel benefits

Ensure you have additional medication and medical supplies in your suitcase

Last items in your carry-on will be most accessible, so pack your passport, ID, ticket, headphones, etc. here

Use Google Flights or another flight search engine to monitor pricing

Even if it costs a little more, try to book a nonstop flight as opposed to one that requires connections
