A packing list eliminates the panic of last-second packing, serves as a handy guide for repacking at the end of the trip, and can be beneficial in the unfortunate event of lost or stolen luggage. Make sure to include the little stuff we tend to forget, such as medicines, cords, gadgets, or small umbrellas.
Pack your prescriptions or OTC drugs, especially those you take regularly and put them in your carry-on bag.
When it comes to jewelry don't take what you don't want to lose, and leave behind the flashy pieces that could attract thieves. If you do take valuable jewelry, be sure to store it in your hotel safe when not wearing it.
Everyone seems to have an opinion but I found that folding gives me the most space! Practice folding like they do in clothing stores - they use that method for a reason. The better the fold, the fewer the creases. The interlocking method of folding clothes is ideal for suitcases. Overlap two pieces of clothing flat and then fold them into each other so that each piece cushions the other to aid in defying wrinkles.
Keep a travel kit perpetually stocked in a waterproof case -- it saves packing time before the trip and aggravation after arrival. And don't fill bottles up to the very top--pressure inside the plane may force the contents to expand and overflow. Also, be careful when it comes to checking aerosols in your checked luggage as they also can explode under pressure.
Pack a scarf, wrap or light jacket for the unpredictable temperatures of plane travel or unanticipated ones during your trip to your destination.
Be sure to put all the electronics (including the correct adaptors and charging cords) that you can't live without during your travels in your carry-on bag. Make sure your electronics are fully charged and that you have downloaded for your airline and your travel documents.
Don't forget the most essential documents or your passports, visas, credit cards, prescriptions. Be sure to pack your important travel documents (passports and other required documents) in a safe and dry location and store them in your hotel safe upon arrival!
