At certain airports there are extra baggage fees which you should be prepared for
. The amount you pay for the extra bags will depend on the airport you are going through and how many bags you have total. A majority of the time you will have to pay extra if you want a second bag checked in or taken with you on the airplane.
You should be able to go on the website of the airport you will be going through to find out this information. It will provide you with all of the details that you need to know regarding extra bags being either checked-in or carried on with you. There are also additional fees for oversized or overweight bags, because special considerations need to be taken when handling them. Usually the fees you are charged correspond to the weight of the items you are transporting. The fee could end up being as low as $20 or over $100 depending on how large or heavy they are. Also you may be charged less if you check in at the inside baggage line versus the outside check-in lane.
Typically these types of bags are stored in separate parts of the plane which are then unloaded upon arrival. You will also need to factor in where you are going when trying to figure out how much you will pay in extra baggage fees. Every airport is different, so it is important to recognize this when you are trying to create a budget for your trip. It's always a good idea to have extra money on hand just in case you don't know how much you are going to have to pay.
The best thing that you can do to avoid these extra baggage fees at the airport is to try and travel as light as possible, not bringing any huge or oversized bags. This will ensure that you don't have to spend a lot of money on extra bags. Almost all airports do charge for extra bags brought through, so you should be prepared for this when travel anywhere. Most of the time you will be able to use either cash or a credit card when it comes to paying these types of fees, although every airport is different with regards to how they handle these fees.
Airlines also may or not have fees for even the first bag that is checked. Southwest and Jet Blue are two airlines that don't charge for first piece of checked baggage. Most of the other ones do.
