There are a few steps you can take to ensure that you aren’t wasting extra money.

When you check your baggage with an airline, the fee is usually $25-30. That fee is typically charged for every unit of checked baggage, so a round trip with one family of four can easily cost more than $200. As you can see, the hidden costs of travelling can add up quite quickly if you’re not careful.

When it comes to airlines, you can easily find a good deal for a couple of round-flight tickets, which will end up being a good deal. Once you add any parking fees, a magazine, a cocktail, and maybe some baggage fees, it can easily go from being a bit pricey to out of control.

The first thing you should do is avoid all unnecessary extras for your journey. Why pay three times what you need to for a cup of coffee?

Beyond the obvious, try to look into airlines that offer fair prices while also being reasonable with extra fees. Many airlines don’t carry checked baggage fees for each passenger’s first bag. If you prefer an airline that does charge more for checked baggage, see what benefits you can get with the airline. Air alliances and airlines offer cards that carry many benefits, including free checked baggage.

Likewise, it is a good idea to pool all your flights with one airline, where applicable. That way you can attain elite status with them and collect loyalty rewards.

Lastly, try to weigh your bags before you go to the airport. If you forget about weight restrictions, you can end up paying significantly more.
