MileIntelWhat Are Upgrade Certificates?
Upgrade certificates are complimentary or earned instruments that elite frequent flyer members can use to move from a lower cabin to a higher one on qualifying flights. Unlike using miles for an upgrade, certificates are typically included as a benefit of maintaining elite status.
Each airline's certificates have different rules about which routes they cover, which fare classes are eligible, and how they clear (confirmed vs. waitlisted). Understanding these details is crucial to getting the most from your certificates.

When to Use Certificates
Use certificates when:
- The flight is long-haul and the upgrade value is high ($2,000+)
- Your certificates are expiring soon
- The miles-based upgrade cost would be prohibitive
- You're flying on a less popular route with better clearance odds
Consider miles instead when:
- The route is short and the upgrade value is low
- You want a confirmed upgrade (certificates often waitlist)
- You're booking for a non-elite companion
- The miles cost is reasonable for the route
Frequently Asked Questions
Upgrade certificates are instruments earned by elite frequent flyer members that allow them to upgrade from a lower cabin to a higher one, often at no additional cost. They come in various forms: Global Premier Upgrades (GPUs), PlusPoints, Systemwide Upgrades (SWUs), Regional Upgrade Certificates (RUCs), and Suite Night Awards (SNAs).
Upgrade certificates are typically earned by achieving elite status in a loyalty program. For example, United 1K members receive GPUs and PlusPoints. American Airlines Executive Platinum members receive Systemwide Upgrades. Marriott Platinum members and above receive Suite Night Awards. The specific certificates and quantities depend on your elite tier.
Global Premier Upgrades (GPUs) are United's traditional upgrade instruments for 1K and Global Services members, valid on international and premium transcontinental flights. PlusPoints are a newer, more flexible upgrade currency that can be used on any United-operated flight — domestic, short-haul international, or long-haul — with the cost varying by route distance.
Use certificates when the miles-based upgrade cost would be high and you have certificates expiring soon. Use miles when you don't have certificates available, when the miles cost is reasonable, or when booking for someone who isn't an elite member. Our Upgrade Calculator can help you compare the value of each option.
Yes, most upgrade certificates expire at the end of the membership year or a set period after issuance. United GPUs and PlusPoints typically expire January 31 of the following year. American SWUs expire based on the qualification year. Always check your specific certificate's expiration date and plan to use them before they expire.
Generally, no. Most upgrade certificates are only valid on flights operated by the issuing airline. United GPUs and PlusPoints only work on United-operated flights. American SWUs only work on AA-operated flights. Delta RUCs only work on Delta-operated flights. For partner flights, you typically need to use miles instead.
