1. Book Your Flight Early
It's a good idea to book your flight in advance to catch the best deals. Studies show that airfares tend to be lower if you book 1 to 2 months ahead of your trip. While there’s no fixed rule, planning your flight booking in advance can save you a significant amount of money.


2. Shopping
When shopping abroad, it's wise to convert and mentally calculate the price of items in your local currency. Only make the purchase if the price seems reasonable. If you're shopping in markets, especially in countries like China or Thailand, don't forget to haggle—you should aim to pay around 2/3 of the initial price the seller offers. For larger purchases, like electronics worth over 300 USD, you’ll need to cover taxes and shipping costs (if applicable).


3. Get Comprehensive Travel Insurance
While no one hopes for mishaps, they can still happen during your travels—such as lost luggage, illness in children, flight delays, food poisoning from unfamiliar dishes, allergic reactions, or even road accidents. In these situations, travel insurance can protect you from hefty costs, and in some cases, it may even reimburse you for unexpected events.


4. Learn About Local Culture
Before traveling to any country, it's important to research local customs and taboos. For example, in Thailand, women are prohibited from touching monks; in Singapore, littering can lead to fines; in the United States, you must ask for permission before smoking; and in any country, you should never shake hands with Muslim women unless invited to do so.


5. What Souvenirs to Buy When Traveling Abroad?
You can purchase local specialties or dry foods as souvenirs, but avoid buying liquid food items. If you plan to buy cosmetics or perfumes, ensure they are under 100ml per bottle, and no more than 10 bottles in total. For souvenirs, the items vary by country, but try to avoid large, heavy items, as shipping fees can add up quickly.


6. Should You Use an ATM Card to Withdraw Money?
The answer is no. It's better to carry enough cash with you, as withdrawing money via ATM can incur high fees along with transaction charges, which can add up and increase your travel expenses. Additionally, there’s a chance your ATM card may not be accepted at certain locations. Some banks even require you to notify them ahead of time if you're traveling abroad.


7. Eating and Entertainment
What to eat and where to have fun are common questions before every trip. Make sure to research your destinations thoroughly. Don’t miss the chance to try street food, which is often delicious, diverse, and affordable. Don’t let food safety concerns hold you back from experiencing these tasty and unique culinary adventures.


8. Luggage
You shouldn’t pack too much luggage, aiming for a total weight of no more than 20kg for checked baggage and 5kg for carry-on. Bring only a few outfits suitable for the climate of your destination, along with essential personal items like headache medicine, anti-diarrheal, allergy medication, toothbrush, toothpaste, towel, and some snacks. If you carry valuable jewelry, make sure to declare it to customs. Also, leave some room in your suitcase to bring back souvenirs.


9. Documents
Make sure to bring all the necessary identification and travel documents, including those related to immigration. Keep the second copy of your arrival/departure form for customs processing when leaving certain countries. For added security, you can leave these important documents at the hotel for safekeeping.


10. Currency Exchange
Exchanging money is a crucial step for any international trip. Make sure to exchange enough currency before you leave. If you can’t exchange the local currency of your destination, US dollars are often accepted. Be cautious about exchanging money at the airport, as the exchange rates are usually less favorable than those in the city.
