Basic Economy tickets usually limit advance seat selection, while standard Economy and higher fares allow customers to select or change seats through United’s website, mobile app, or during check-in.

United provides multiple upgrade options. MileagePlus® members may be eligible for complimentary upgrades on select domestic flights, with priority based on elite status, fare class, and availability. Paid upgrades can be purchased using cash or MileagePlus miles at booking, after ticketing, or during online check-in. United also offers PlusPoints upgrades for Premier® elite members, which can be applied to domestic and international flights.

Same-day upgrades may be available at the airport if premium seats remain open. To increase upgrade chances, travelers should add their MileagePlus number to the reservation and check upgrade availability frequently. Overall, United Airlines’ seat selection and upgrade system combines flexibility, loyalty benefits, and multiple paid options for a more comfortable journey.
