In accordance with Transportation Security Administration regulations, each commercial airline passengers is limited to one carry-on bag and one personal item such as a purse, laptop or camera, so you won't be able to travel with two suitcases in your plane's cabin. The one bag you'll be allowed to take on board will be subject to weight and dimension restrictions. If a suitcase you want to travel with as carry-on luggage exceeds your airline's limits, you'll be asked to check it and pay a fee. Restrictions and fees vary by airline. Many airlines have tightened their carry-on policies since introducing checked luggage fees.
Airlines will typically allow you to travel with two suitcases as checked luggage, but most will make you pay for the pleasure. Many carriers increase their charges in line with the number of bags passengers carry. As such, you can expect to pay more for your second checked suitcase.
As with carry-on luggage, checked suitcases are subject to weight and dimension restrictions. Traveling with cases that are either too heavy or the wrong size can end up costing you dearly. Measure your suitcases before you leave your home to avoid any nasty surprises at the check-in desk.
Traveling with hand luggage only will usually save you money, but if you must fly with two suitcases, seek out carriers with the lowest baggage fees. Some international airlines and a small number of domestic carriers offer free checked first and second bags. You'll typically pay through the nose if you want to check three or more bags no matter what airline you fly. Always pay for checked luggage when booking your flight online. You may have to pay more if you leave it until you're checking in.
If you're a frequent flyer, signing up to your favorite airline's loyalty program could help you save money on baggage fees. Many carriers reduce or eliminate checked luggage charges for loyalty program members. Your airline's loyalty club comes with other perks, such as miles, priority boarding and flight upgrades.
