Are you planning a trip? With most airlines charging baggage fees for checked luggage and even some charging a fee for carry-on bags, travelers are forced to spend more and more on their airplane tickets. Here, I'll show you a simple way to avoid paying for your checked-luggage which could save you around $50 per person for a round trip.

Baggage fees are on the rise and they make you want to think twice before booking your flight. But just how much are Americans spending on baggage fees? In the first quarter of 2013 U.S. airlines earned $800 million in checked luggage fees, according to the US Department of Transportation's Bureau of Transportation Statistics. Delta (DAL) ranked the highest, earning approximately $192 million in baggage fees during the first quarter of 2013. United (UAL) and US Airways (LCC) followed close behind earning $143 million (United) and $130 million (US Airways) in checked baggage fees.

But just how much are airlines charging per checked bag? The airline that charges the most for the first checked bag is Spirit Airlines with a $45 fee, the second checked bag costs $55, and you will be charged $100 for an additional bag. American Airlines charges $25 for the first checked bag, $35 for the second, and $150 for an additional checked bag. Overweight baggage fees are even higher, ranging from $50 (Alaskan-Horizon Air) to $100-200 (United Airlines).

Paying for checked luggage started in 2008 when American Airlines started charging a $15 fee for a first checked bag, and many airlines quickly followed suit. In 2010, Spirit Airlines imposed a carry-on bag fee. This year, in 2016, the only two big U.S. airline companies that do not charge a baggage fee for checked luggage are JetBlue Airways (first checked in bag free) and Southwest Airlines (which allows you to check in two pieces of luggage for free). JetBlue is currently changing their first checked bag policy, and may remove the free first checked bag benefit for low cost tickets in 2015. How can you avoid paying for your checked baggage? I'm going to explain how you can bypass baggage fees by paying for your flight with the right kind of credit card.

One of the easiest and best ways to get free checked baggage is by purchasing your airline ticket with a frequent flyer credit card. Some frequent flyer credit cards offer the first checked bag free of charge as a special benefit to card members.

United MileagePlus® Explorer Card, issued by JPMorgan Chase (JPM), lets you check your first bag for free and that of another companion on the same reservation. This saves you $50 per person on a round trip. This card also offers lots of bonus miles if you spend more than a certain amount with it. For example, you will receive 30,000 bonus miles if you spend $1,000 in the first 3 months of card membership. You can earn 10,000 bonus miles every year when you spend $25,000 in net purchases made with this card. You can even earn an additional 5,000 bonus miles if you add another authorized cardholder to your account and make a purchase within the first 3 months of opening your account. When purchasing United air tickets through the airlines website, you will earn double (2) miles on every $1 you spend and 1 mile for every $1 spent on other eligible purchases. There is no limit to the amount of miles you can earn and accumulate, so the more you spend using your United MileagePlus Explorer Card, the more you earn.
