Every upgrade that you have seen being awarded on a sold-out Delta flight has had a lot more going on behind the scenes, a process that has ranked all passengers well before the flight has departed.
At the same time, your own status as a Medallion member, fare class, or the Reserve card in your pocket could prove to be much more valuable than you think, provided that you know how to make use of it properly. Missing out on making the right decisions while booking your ticket may cause an eligible upgrade seat to end up getting assigned to a different passenger entirely.
Before you miss out on another upgrade opportunity purely based on hope, this blog post gives you an insight into the entire process of how upgrades are prioritized and cleared on Delta and what options you still have left, despite not having elite status.
The policy that governs Delta Airlines' upgrade system creates a dichotomy between two sets of travelers. Firstly, there is Medallion members and cardholders of Delta's premier Amex program who can be upgraded to a better class at no additional costs if space permits. The other set is everybody else who can also be upgraded, but for a price either in miles, cash, or flying with somebody who qualifies for free upgrades.
Here are some basic parameters that influence the policy in question in general:
It's important to understand these concepts because that's the basis of everything covered in this guide, since the upgrade paths for most other things are dependent on this system.
In addition to affecting the ticket cost, Delta's fare class affects the upgrade priority and eligibility. There are letters attached to each booking indicating the particular fare type, and these letters determine how high one is in the upgrading priority list. The Y and B fare types indicate that the passenger is traveling with a full-fare economy ticket and thus have a higher priority than M, H, Q, and K which are discounted. L, U, T, X, and V are generally deep-discount economy tickets and have the lowest upgrade priority.
Understanding the fare class for the Medallion passengers could help them set their expectations accordingly. If a Diamond member buys a Y fare, he is almost certain to upgrade above the other Diamond member who bought a V fare on the same flight. That is why there are people who opt for the more expensive flexible fare type because of the upgrade priority.
When there are more upgrades available than passengers on the wait list, Delta does not simply select the lucky ones randomly. Instead, it operates according to a hierarchy, allocating seats based on the priority order, until all upgrade seats are allocated.
Here is an approximate order of the hierarchy, starting from the most important one:
|
Priority Rank |
Factor |
Why It Matters |
|
1 |
Medallion tier |
Diamond and Platinum members sit above Gold and Silver |
|
2 |
Fare class purchased |
A pricier fare within the same cabin outranks a cheaper one |
|
3 |
Million Miler status |
Lifetime mileage milestones can push you ahead of others at the same tier |
|
4 |
Top-tier Delta Amex cardholding |
Reserve cardholders edge out same-tier elites without the card |
|
5 |
Corporate travel codes |
A recognized employer code on the ticket adds priority |
|
6 |
Medallion Qualification Dollars earned this year |
More MQDs banked so far this year can break a tie |
|
7 |
Timing of the request |
Among otherwise equal passengers, earlier requests tend to win |
It is worth remembering, however, that this order is not set in stone but merely a guideline Delta uses, and in particular situations – for example, the number of upgrades available for the given flight – things may be different than expected.
Time plays as important a role as the Medallion rank itself, as no matter how high your Medallion status is, your upgrade cannot clear until it is processed by the computer. The times of clearing depend on both the cabin you want to upgrade to and your Medallion rank.
The timing of clearance for upgrading to Delta Comfort+ is usually as follows:
|
Medallion Tier |
When Comfort+ Upgrades Typically Clear |
|
Diamond |
Very shortly after the ticket is booked |
|
Platinum |
Very shortly after the ticket is booked |
|
Gold |
Starting around 72 hours before departure |
|
Silver |
Starting around 24 hours before departure |
Moving into First Class or Delta One tends to open later in the process:
|
Medallion Tier |
When First/Delta One Upgrades Typically Clear |
|
Diamond |
Around five days before departure |
|
Platinum |
Around five days before departure |
|
Gold |
Starting around 72 hours before departure |
|
Silver |
Starting around 24 hours before departure |
And if you are monitoring your waitlist and have not seen any movement yet, that is probably because of this. It’s just that the Diamond and Platinum members get access to the waitlist much earlier than the Gold or the Silver members, and an open seat will only become available to people at your tier level.
Besides status and fare type, there are a number of tactics one may apply in order to enhance chances of getting upgraded. Choosing to fly off-peak will result in lower chances of having elite passengers fight for upgrades along with you. Late night or early morning flights are likely to be less busy with upgrade requests than flights taken at the peak time of business travelers’ activity.
Choosing lesser-traveled routes is likely to result in a significantly higher probability of getting upgraded. A flight from Atlanta to some small-town destination is going to have greater chances of having empty seats in First Class than a flagship route, such as JFK to LAX. Another factor that may influence one’s chances of being upgraded is advance ticket booking.
Not all travelers can ask for upgrade certificates because they are intended for Platinum and Diamond Medallion members as part of the annual benefits selection process. Once you become one of these members, you are provided with a variety of perks from which you are allowed to choose and upgrade certificates are among them.
There are two types of upgrade certificates available:
A Platinum member choosing to use this benefit receives a pack of regional certificates whereas Diamond members have a choice between a combination of global and regional certificates. Having received these certificates, you will have to use the phone rather than the website to attach them to your booked ticket since it cannot be done online. Furthermore, having such certificate does not guarantee your upgrade if there are no seats available.
Two small pointers that really matter. If your certificate is not able to help you board directly in the premium cabin, you’ll find yourself boarding in the middle cabin first and then waiting separately to board in the premium cabin. And even if your certificate is not used because of lack of space, it doesn’t go to waste and comes back in your account.
In addition to offering upgrades on its own aircraft, Delta, being a SkyTeam airline, also offers limited upgrade possibilities on the partner airlines' flights. In addition to the SkyTeam partnership, Delta maintains several other independent partnerships, and upgrades are offered based on a global upgrade certificate; however, there are only a few partners who accept such certificates at the moment, including some major international airlines that are accessible through Delta's partnerships.
Specifically, one such partner provides upgrades to domestic flights to Mexico and between Mexico and adjacent destinations such as Central America and the Caribbean. In this case, most fare classes including award fares can be upgraded to a business-class seat on the partner's aircraft; however, the seat will only recline and not lie flat.
The straightforward truth is that there is little "asking" required if you are qualified for one. Once you have either Medallion status or own a premium Delta credit card, you will get automatically put on the upgrade list as soon as your ticket gets booked, so no asking of any kind is necessary in order to get into consideration. Nevertheless, a few tips can make your situation a bit easier:
If you're not even a Medallion member, your chances of getting a free upgrade from asking at the gate are close to zero. Instead, it would be better to look into the paid upgrades listed below.
Without Medallion status, however, there are still a few feasible ways to get that improved seat, although none are entirely certain or, for that matter, free of charge.
The truth of the matter is that the free upgrade with no spending and no status really does not exist but is a privilege of just a few travelers. For everybody else, there is a choice of earning status, paying an annual card fee, or paying for the seat outright.
Once all this information is compiled, the most prominent issue is clear that is getting a free Delta upgrade is largely dependent on one’s positioning in a relatively predictable hierarchy that favors status. While followed by fare and then miles, with certificates and credit cards making up for the rest. Once this step is done, it is simply a question of matching oneself to the relevant route. Look at your Medallion status, make sure that your fare isn’t Basic Economy, and pick a relevant route from above.
Frequently Asked Questions
Does Delta offer free upgrades to all passengers?
No, free upgrades are offered only to Medallion elite members and to owners of Delta Amex cards of the highest level. All other passengers should pay with cash, miles, or be companions of eligible passengers.
Which factor determines the quickest route to getting to the top of the upgrade list?
The highest Medallion tier is the most important one, next is the fare class of the ticket and Million Miler status. The Delta Amex card at Reserve level allows getting a priority over elites of the same tier but without such card.
Can I use my upgrade certificate for international flights?
Certificates work within the United States and adjacent territories. Global certificates are provided only for Diamond Medallions and allow upgrades to international destinations, such as Europe and Asia.
Can Basic Economy fares be eligible for any complimentary upgrade?
No, since Basic Economy tickets are not included in Delta's complimentary upgrade program at all.
