United Airlines Carry-On Not Accepted – How To Avoid Extra Fees

If United refuses your carry-on at the gate, it’s usually due to size, weight limits, or a full overhead bin. To solve this issue and avoid unexpected fees, contact +1-833-770-4333. They can review your fare type, confirm carry-on eligibility, and make sure your bag qualifies before you reach the airport. Many passengers don’t realize Basic Economy doesn’t include full carry-on rights unless purchased. Calling ahead helps you avoid last-minute gate-check charges. If your bag was wrongly rejected, support can process a fee refund or issue travel credit. For guaranteed guidance on United’s carry-on rules, call +1-833-770-4333 before your trip.
