Contact your airline to determine the size and weight restrictions and the amount of luggage you can carry on board with you. Be sure to label all luggage with your name, address, and telephone number.
In case your luggage is lost, you should carry a small flight bag with personal hygiene items, a change of clothing, and any valuables. Keep your passport, money, and other valuable items with you at all times. Immigration documents must be presented at the port of entry to the United States.
