You can also ask a United representative at the gate about changing your seat or buying Economy Plus® seating, if available and if you haven't bought a Basic Economy ticket. It's sometimes possible to change seats once you're on board the aircraft, but please don't change seats without asking a flight attendant first.

Yes, you can ask for a different seat at the gate, and in 2026, this remains a common practice for travelers looking to improve their comfort. When you arrive at the boarding area, you can approach the gate agent and politely inquire if there are any available seats that better suit your needs, such as an aisle, window, or a row with an empty middle seat. Gate agents have the most real-time information regarding "no-shows" and last-minute cancellations, which can free up prime real estate on the aircraft just before boarding begins. However, success often depends on your fare class and elite status; those with frequent flyer perks are prioritized for complimentary "preferred" seating. If you are traveling on a Basic Economy ticket, the agent may be more restricted by airline policy, but it never hurts to ask. If you are seeking an exit row, be prepared to answer verbal safety questions to confirm you are willing and able to assist in an emergency.
