Even on a long trip, you don't need a lot of heavy suitcases. You only need two bags-a carry-on bag and a check-in bag. Here is some advice for packing them.

Carry-on bag

• Your carry-on bag should be small and light.

• The most important things for your trip (passport, boarding pass, airline tickets, money, credit cards, cell phone, keys, etc.) should go in your carry-on bag.

• You should pack valuable things, such as a laptop or jewelry, in your carry-on bag.

You should bring a change of clothes in case your luggage is delayed.

• You should also take any medicine you need in your carry-on bag.

• Bring snacks to eat on the plane. Cookies, nuts. and dried fruit are good. Don't bring chocolate-it's very messy. For long trips, bring a sandwich.

And don't bring water--you can't take it through security. You should buy some at the airport before you board the plane.

• Remember to bring a good book or your tablet.

Check-in bag

• Your check-in bag should be strong.

• Your clothes, shoes, and other everyday things should go in your check-in bag.

• Make a list to help you remember everything.

• Pack your bag early-don't pack on the same day as your trip!

• Think about the weather. Do you need a coat and gloves, or T-shirts and shorts? Choose the right clothes! You should pack your clothes inside plastic bags.

• Put your name and your hotel's address and telephone number on your bag. You should put this information inside the bag, too.
