Traveling by plane isn’t affordable in most cases to begin with, but checked bag fees can cause costs to spin out of control. This especially applies when you’re flying with your family, as fees for checked baggage are charged on both ends—on your way to your landing place and on the trip home.

How much will you spend to check your baggage to your destination? Since most airlines charge a fee of $30 for a checked bag, you’ll have to pay $90 for a family of three for each leg of their journey.

This may not seem high-priced to some, but for most people, we’re talking about a significant additional expense that could be used on something else. The worst part is when these fees catch you by surprise.

Luckily, checked bag fees are easily avoidable with a bit of prior research and a plan in mind. If you want to travel by plane this year without paying extra for your baggage to come along, this article is for you!
