GET THE MOST OUT OF YOUR UPGRADE CERTIFICATES
THE CERTIFICATE GUIDE:
Searching For A Seat Upgrade?
Upgrade availability isn’t always better in advance, and the seat map availability does not necessarily match upgrade availability. This means open seats in the seat map are not always eligible for upgrades, as they might still be available for purchase.
On The Waitlist?
While it’s possible for upgrade requests on the waitlist to be cleared before you get to the gate, it is more likely that they will be cleared at the gate prior to departure. If your Certificate does not clear, it will be automatically reissued to your account. Learn more about Waitlisting.
Wondering About A Date Or Destination?
Due to extremely high demand, fewer upgrades are typically available during peak days and times, such as holiday travel, in certain markets with very long flight times including Sydney, Tel Aviv, and Johannesburg.
ADDITIONAL RULES:
Finding Flights
Upgrade Certificates can be used on any Delta-operated flight and select partner-operated flights.
Traveling Together
You can use an additional Upgrade Certificate for one travel companion on the same reservation.
Enjoying Priority
Upgrade Certificates receive higher priority than Medallion Complimentary Upgrade requests and clear off the waitlist in order of Medallion Tier, then by the day and time your request was added to the waitlist.
Ticket Eligibility
Upgrade Certificates cannot be used for Award Travel or tickets booked in Basic Economy (E).
Redemption Period
Upgrade Certificates expire a year after they are selected. Certificates must be used on flights flown within the 12-month period—otherwise, the Certificates will expire.

No availability in your preferred cabin when booking your upgrade? Get on the waitlist to ensure your upgrade clears if seats become available.
Here is how it works:
- Call Delta Reservations to book your upgrade – 1-800-323-2323 in the U.S. View worldwide phone numbers.
- If there is currently no upgrade availability for your flight, request to be put on a waitlist.
- Open seats in the seat map do not necessarily mean they are available for upgrades (they might still be available for purchase) so keep in mind that seat map availability does not necessarily match upgrade availability.
- If a seat becomes available in the cabin you are waitlisted for, your upgrade will clear automatically.
- One Upgrade Certificate can put you on a single waitlist or multiple waitlists – from a specific cabin on a particular flight to multiple cabins on multiple flights. But, your upgrade will only clear off of ONE waitlist and will be based on the FIRST seat that becomes available across all of the waitlists the Certificate is listed on.
- For example, if you are waitlisted on DTW-NRT and also JFK-LAX with one certificate, if a seat becomes available on the DTW-NRT flight you will be upgraded on that flight and you will no longer be waitlisted on the JFK-LAX flight as the certificate has been used.
- Or, if you are waitlisted for both Delta One and Delta Premium Select on your DTW-NRT flight, if a seat in Delta Premium Select becomes available first, you will be upgraded to Delta Premium Select and you will no longer be waitlisted for Delta One as the certificate has been used.
- For example, if you are waitlisted on DTW-NRT and also JFK-LAX with one certificate, if a seat becomes available on the DTW-NRT flight you will be upgraded on that flight and you will no longer be waitlisted on the JFK-LAX flight as the certificate has been used.
- Once your upgrade clears off the waitlist, your certificate will be considered used.
- If no seats become available before departure, your certificate will be returned to your account for you to use on a later flight.
Waitlist Options:
Use this chart to understand your different options for being added to the waitlist depending on the cabins available and the number of certificates you have. This is meant to be a general guide, and your options may have to adjust if, for example, you’re traveling with a companion, which would require another certificate.Number of Upgrade Certificates in your account:
