The main ways to upgrade to first class on United
- Pay cash at booking — buy a First or Domestic First fare outright; simplest and always confirmed.
- Cash upgrade after booking — United often offers a paid upgrade on the cheaper cabin via your trip details.
- Mileage / PlusPoints upgrades — MileagePlus members can use miles or PlusPoints to upgrade eligible fares.
- Complimentary elite upgrades — Premier members may clear into First automatically based on status and availability.
- Last-minute upgrade at the gate — sometimes discounted if seats are still open.

How to request a United first class upgrade
- Check your fare's eligibility — Basic Economy usually can't be upgraded.
- Look for a paid upgrade offer in your trip details after booking.
- Add yourself to the upgrade list if you have status or PlusPoints.
- Compare cash vs miles — sometimes paying cash is the better value.
- Confirm seat assignment once the upgrade clears.
First class vs business class on United
On domestic flights, the premium cabin is "United First." On long-haul international routes, the top cabin is United Polaris business class. If your route is international, the smarter target may be business — see the cheapest way to upgrade to business class on United.
If an upgrade isn't worth it
Sometimes the upgrade math doesn't work, and you're better off choosing a great Economy Plus seat instead. We break down United economy seat selection fees so you can pick the best spot without overpaying. Booking timing matters too — see the best time to book a flight for the cheapest fare.
What you actually get in United First
Before you spend miles or money, it helps to know what the upgrade buys. On domestic United First you can generally expect:
- Wider seats with more recline and noticeably more legroom than Economy.
- Priority check-in, security, and boarding so you're settled before the crowd.
- Complimentary snacks or meals and drinks depending on route and time of day.
- Free checked bags and earlier baggage delivery.
- Dedicated overhead bin space near your seat.
On shorter hops the difference is mostly comfort and priority; on longer transcontinental flights, the meal service and seat width make a far bigger difference — which is where paying for an upgrade tends to feel most worth it.
Timing your upgrade for the best odds and price
Upgrade availability and pricing shift constantly. To improve your chances:
- Book an upgrade-eligible fare from the start — not Basic Economy.
- Add yourself to the upgrade list early if you have status or PlusPoints.
- Fly off-peak. Midweek and early-morning flights have more open First seats.
- Re-check 24–48 hours out, when paid upgrade prices often drop.
- Have us monitor it so you don't miss a price dip.
