There’s a chance you encountered a message like this when checking in for a Delta Air Lines trip involving Global Upgrade Certificate (GUC) or Regional Upgrade Certificate (RUC):
So, what gives?
Using an Upgrade Certificate? Your Ticket Must Be Reissued
Upgrade Certficiates can’t be applied online directly by SkyMiles members. You must call Delta reservations (or your Medallion line) and ask a representative to do it for you. (Delta told us we’ll be able to manually apply Upgrade Certificates online sometime in the near future.)
Once an Upgrade Certificate is applied to your trip, your ticket needs to be reissued. Some Delta phone representatives know this and can do it on the spot.
Others don’t. They just apply the certificate and send you on your merry little way. You might assume they reissued your ticket.
That’s what I did when applying an expiring Regional Upgrade Certificate to a recent trip. (Assuming isn’t often a good practice.) I forgot to ask the representative to reissue the ticket.
Several months later, I tried using the Fly Delta app to check in for that flight. I received the “Oops! We’re Sorry…” message. I didn’t have any luck on Delta.com, either.
So, I called Delta and spoke to a rep. She told me the ticket needed to be reissued because I used a Regional Upgrade certficate. (You can’t check in without, you know, a valid and issued ticket). Unfortunately, she couldn’t do it herself. She had to get in touch with another department.
That took a while.
Much to my surprise, my Regional Upgrade Certificate actually scored me a confirmed upgrade to First Class well before my upgrade window opened! (Can you believe it?!)
When you apply an Upgrade Certificate to your Delta Air Lines flight, ensure the Delta rep with whom you speak reissues your ticket. Otherwise, won’t be able to check in. Delta says we can add Upgrade Certificates ourselves in 2023. Hopefully, this won’t be a problem anymore.
