I recently booked a United flight and immediately wanted to see if I could snag a better seat. I called 877-297-0699 and also checked the app — and let me tell you, it was simpler than I expected! If you’re wondering how to request a United upgrade after booking, here’s my step-by-step experience.
Before diving in, it’s important to understand the types of upgrades you can request:
As a MileagePlus elite member, I’m eligible for Complimentary Premier Upgrades on domestic flights. These upgrades depend on your fare class and status. For example, as a Premier Silver, my upgrades often clear 24 hours before departure.
United’s PlusPoints program allows elites to upgrade using points instead of miles. Domestic upgrades usually require fewer points, while international flights might need more. Pro tip: check United’s official PlusPoints guide to see what’s needed for your flight.
If you’re not an elite, you can still use MileagePlus miles to request an upgrade. I once redeemed miles to move to Business Class on a long-haul flight — it was worth every mile!
You can request an upgrade through the United app or website:
Log in to your MileagePlus account.
Go to “My Trips” and select your flight.
Look for the “Request Upgrade” button.
Visual Tip: A screenshot or mockup of the app showing the upgrade button is super helpful here.
Once you tap “Request Upgrade,” your status will show on the upgrade list. It’s that simple. I’ve had upgrades clear within hours when the flight wasn’t full.
Sometimes, speaking directly to an agent helps. Dial 877-297-0699 — they can confirm eligibility, add special requests, or clarify your options. I found that calling in the morning often yields faster responses.
After requesting, keep an eye on your upgrade status:
Check the app frequently.
Domestic upgrades often clear 12–24 hours before departure.
International upgrades may clear 24–48 hours prior.
Example: On a recent domestic flight, my upgrade cleared 12 hours ahead of time. For an international trip, it cleared just a day before.
A few tips that helped me get upgraded more often:
Book earlier in the day when flights are less crowded.
Choose eligible fare classes.
Maintain elite status with MileagePlus.
Monitor the app frequently and be ready to call 877-297-0699 if needed.
Requesting a United upgrade after booking doesn’t have to be stressful. Know your options, use the app or website, call 877-297-0699 when needed, and monitor the upgrade list.
