My advice is-always travel light! I hate to carry heavy bags. Just take the minimum. There is an old saying:Breakfast in Berlin. Dinner in Delhi. Bags in Bangkok! So,don't pack anything important in your check-in bag; put important things in your carry-on bag. You don't want to arrive home without your house keys. Another tip-don't use expensive suitcases. People don't steal dirty old bags.Finally,here's good little tip-tie a sock or brightly colored string to your bag. Why? So you can quickly see your bag on the airport carousel
