I remember calling 877-297-0699 one hectic morning, hoping for a free upgrade on my United flight. To my surprise, I learned that a few insider strategies and a little planning could dramatically increase my chances — without spending a dime. If you’ve ever wondered how to get a free upgrade on United, here’s what I’ve discovered from personal experience and industry insights.
United offers several ways to fly in comfort for free:
Complimentary Premier Upgrades (CPU): Automatically available for elite members on domestic and select short-haul flights.
PlusPoints Upgrades: Free upgrade credits for Premier Platinum and 1K members that can be applied to both domestic and international flights.
MileagePlus Award Upgrades: Redeem miles instead of cash, which can feel almost free depending on the redemption value.
Free upgrades are most common on domestic and transcontinental flights. International long-haul upgrades are trickier, though PlusPoints can help.
Visual idea: Chart comparing CPUs, PlusPoints, and MileagePlus upgrades with eligible routes.
Your Premier tier largely determines your upgrade odds: 1K clears first, followed by Platinum, Gold, and Silver. I’ve seen friends with Platinum status get upgrades before Gold members, even on the same flight.
Higher fare classes like Y, B, or M tend to clear faster. Discounted fares may leave you waiting, even with elite status.
Booking early and checking in promptly increases your chance of clearance. Off-peak flights and mid-week travel often clear upgrades faster than heavily booked holiday flights.
PlusPoints are an incredibly useful tool for eligible elites. I once applied PlusPoints to a transcontinental flight and woke up to an overnight upgrade confirmation. Unlike complimentary upgrades, PlusPoints give you more flexibility, especially on long-haul routes or high-demand flights.

Call 877-297-0699 if you’re unsure about your eligibility, fare class, or waitlist position.
Personal anecdote: “One of my upgrades cleared just a few hours before boarding because I stayed on top of the waitlist and applied my PlusPoints strategically.”

Free upgrades on United are possible with elite status, the right fare class, and smart planning. By understanding how CPUs and PlusPoints work, monitoring your waitlist, and timing your requests carefully, you can fly more comfortably without extra cost.
