(e.g., JFK–LAX, JFK–SFO, BOS–SEA)
Who is eligible

 Platinum Medallion
 Gold Medallion (rare, depends on availability)
These upgrades usually clear close to departure if inventory remains.
3. Global & Regional Upgrade Certificates
(Guaranteed When Space Exists)
If you’re a Medallion elite—especially Platinum or Diamond—this is your strongest upgrade
weapon.
Regional Upgrade Certificates (RUCs)

Global Upgrade Certificates (GUCs)
 Valid on international Delta One flights

These cash offers are sometimes shockingly affordable—especially:
 48–72 hours before departure
 When Delta One has unused seats
Real traveler insight:
Upgrades are cheapest when demand is low.
Mid-week flights often have better offers than weekend departures.
5. Upgrade at the Airport (Last-Minute)
If seats remain unsold, Delta sometimes offers same-day upgrades:
 At check-in kiosks
 At the gate
 Via the Delta app
These are usually the lowest priced cash upgrades you’ll find.
Good for:
Travelers who are flexible and willing to wait until the last moment.

Some discounted fares cannot be upgraded with miles or certificates.
Fares that allow upgrades
 Main Cabin
 Comfort+
 Premium Select (on international routes)

Pro Tips to Increase Your Odds of Getting a
Delta One Upgrade

Delta uses the “R” fare class for upgrades.
If R > 0, upgrades are likely.
✔ Fly from alternate airports
Example: BOS–LHR often has more availability than JFK–LHR.

Holiday travel makes upgrades harder.
✔ Join SkyMiles if you haven’t already
Status improves your position on the upgrade list.
