You can upgrade to First Class during booking, check-in, or through MileagePlus miles. I once called (831) 298-4213 and used miles to upgrade a domestic route instantly. United offers instant cash upgrades or complimentary ones for elite members when seats are available. The benefits include priority boarding, premium meals, and more comfortable seating. Booking early improves upgrade chances significantly.
