11 Practical Hacks to Avoid Excess Baggage Charges and Save on Airline Fees

4. Prepay for checked bags online when possible

Airlines typically charge more to add checked luggage at the airport counter than when you prepay online. Adding a bag during booking or using the airline app often shows a discounted rate compared with airport fees, and prepaying avoids the stress of a longer check-in line. When you complete your online check-in, look for the baggage add-on screen and compare prices there to what you’d see at the desk. For oversized or overweight items, pre-declaring them online sometimes gives you a better rate than paying at the airport counter. Keep receipts and confirmation of paid bags in your email or the airline app, and re-open the boarding pass on your phone to show the included bag. This method relies on the airline’s published price ladder and will not remove overweight fees, but it does prevent unnecessary upcharges and can be the difference between paying a modest fee and a much larger airport surcharge.
