Should any of your carry-on items be too large, you will be required to check them in for a fee. If you are wondering how much you will be charged for certain items, United offers a baggage fee calculator that will help you plan. 

When measuring your baggage, be sure to include the handles and wheels in the total. If your baggage exceeds the maximum measurements, you will be required to check it in for a fee. 

In the event you need to gate-check your bag, an staff member will give you a green tag. Your baggage will then be handled by a handler and stowed in the plane’s cargo compartment. Upon landing, you will be able to pick your baggage up at the gate/jetway rather than at baggage claim. 

If you are traveling with medication you may need during the flight, it is advised that you carry them in one of your personal items, such as a small bag or purse so that you will have quik and easy access to them during your flight. In addition, if you are traveling with personal vaporizers and/or  e-cigarettes, you must place them in your carry-on bag or personal item. These items are not allowed to be checked in.
