Take time to list down all the important belongings that is necessary in your trip. Like documents, medicine, clothings, shoes and toiletries.
After listing, secure all the things that are in your list. Put them in one place so that you can recheck your belongings.
You must have to have a plastic bag or plastic pouch for your toiletries. It is advisable to have a plastic bag for security purposes. If the security official would inspect your things you can easily show them your belongings without any hassle. Plus, you can easily take out the things that you need without rummaging it.
Upon packing your belongings in your luggage it is best to pack at the bottom the things that you seldom used and on top for the things that you need most. To save space in your luggage, try to roll your clothes.
It is unwise to put your documents in your luggage. Best to have a hand carry bag for your important documents and medication for immediate use.
