Not all airlines have the same baggage policy. Some include one checked bag for free, while others even charge for cabin baggage. Before booking your ticket, compare the policies of different airlines to avoid unpleasant surprises.

If possible, avoid checking in a bag. Most airlines allow one free carry-on bag, as well as one personal item (such as a backpack or handbag). Choose a bag that meets the maximum dimensions allowed and use optimal folding techniques to maximize space.

• Use compression bags: They help reduce the volume of your clothes and save space.
• Wear your heaviest clothes: Put your jackets, bulky shoes and sweaters on you instead of in your suitcase.
• Use all available space: Stuff your shoes with socks or underwear.

Some airlines offer additional baggage allowances to members of their loyalty programs. Even as an occasional traveler, you may be eligible for discounts or waivers on baggage fees.

Some credit cards include a waiver of baggage fees if you book your flight with them. Check the terms of your card before purchasing your ticket.

Airlines often charge exorbitant fees for excess weight. Check your airline's restrictions and weigh your suitcase before you go.

If you are traveling with several people, distribute heavy items between suitcases to avoid any single piece of luggage exceeding the authorized limit.
