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 a 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.
