Baggage If you travel by plane, most airlines will allow you to send two suitcases on the same flight as checked luggage, plus one extra bag as cabin luggage or “carry-on.” Weight limits vary from airline to airline. Check with your travel agent or the airline for specific policies. Some countries also have different regulations. You may consider packing a one-day supply of clothing and other necessary items in your “carry-on” bag in case your luggage is delayed or misplaced during your trip. Make certain you carry your valuables with you or in your carry on luggage. Never put money, jewelry or important papers (such as immigration documents) in luggage that you check. Always carry these items with you while traveling!
