You're sitting at the gate, staring at those wide, quilted leather seats in First Class while clutching a boarding pass for seat 34B. We've all been there. The legroom in the back is fine, I guess, but once you’ve tasted the pre-departure sparkling wine and actually had space to open a laptop, it’s hard to go back. If you are wondering how do i request upgrade on delta, the answer isn't just one button. It’s a mix of status, timing, and sometimes just knowing where to look in the app.
Delta Air Lines has one of the most sophisticated—and frankly, sometimes frustrating—upgrade systems in the industry. It isn't a "one size fits all" situation. Are you a Medallion member? Are you flying on miles? Did you buy a Basic Economy ticket? That last one is a dealbreaker. If you bought Basic Economy (those E-fare class tickets), stop reading now. You aren't getting an upgrade. Delta is very firm about that. But for everyone else, there is a path forward.
The Medallion Shortcut: Automated Requests
Most people asking how to get that bump up are looking at the Medallion program. If you have Silver, Gold, Platinum, or Diamond status, the "request" part is mostly handled during booking.
When you buy your ticket on Delta.com or the Fly Delta app, there’s a little checkbox for "Request Upgrade." Check it. Always. Even if you think the flight is full. People miss connections, people cancel, and sometimes the algorithm just smiles on you. Once that box is checked, you are on the list. For Medallion members, the window opens based on your tier. Diamond and Platinum folks get their cleared upgrades starting 120 hours (five days) before departure. Gold gets 72 hours. Silver gets 24.
But here’s the kicker: just because you're eligible doesn't mean it happens automatically. I’ve seen Diamond members sit in Comfort+ because they forgot to opt-in for the First Class list specifically.
What if the upgrade doesn't clear early?
If the window passes and you're still in your original seat, don't panic. You move to the "Gate Standby List." This is the digital queue you see on the screens at the airport or in the "Upgrades" tab of the app. This list is a battlefield. It’s ranked by Medallion level, then fare class, then whether you have a Delta SkyMiles Reserve American Express card, and finally by the time of your request. It’s brutal. Being a Gold Medallion on a Monday morning flight from Atlanta to New York means you might be number 45 on a list of 50 for two available seats.

How Do I Request Upgrade on Delta Using Miles?
Maybe you don't fly 50,000 miles a year. That’s fine. You can still get out of the main cabin.
Delta offers something called "Mileage Upgrade Awards," though they are becoming rarer and harder to find. These are different from just clicking "Upgrade with Miles" in the app. To truly use a Mileage Upgrade Award, you usually have to call Delta's reservations line. You’re looking for specific "Global" or "Regional" upgrade certificates if you're a high-tier flyer, but for the average person, you're looking at a straight mileage buy-up.
Open the app. Look at your trip. If there is a button that says "Select Seat" and you see First Class or Delta One seats with a price tag in miles (e.g., 15,000 miles or $175), that is your request. You click it, you pay, and it’s instant. This isn't a "request" in the sense of waiting; it's a confirmed transaction.
Honestly, sometimes the mileage offers are a steal. I once saw an upgrade from Atlanta to Quito for 8,000 miles. Other times, they want 80,000 miles for a two-hour hop to Orlando. Don't do that. It’s a waste of your hard-earned SkyMiles.
The "Global and Regional" Game for Power Users
If you are a Platinum or Diamond Medallion, you get Choice Benefits. One of those is Upgrade Certificates. These are the "Golden Tickets" of the Delta world.
How do you use them? You can't just click a button and be done. Well, you can apply them online now—Delta finally updated their tech—but it still often requires a phone call to make sure the "reissuing" of the ticket happens correctly.
- Go to your profile on Delta.com.
- Find your certificates under "Wallet."
- Search for a flight. Look for the "First Class available with Upgrade Certificate" text.
- Apply it at checkout.
If you’ve already booked, go to "My Trips," and there should be a link to "Apply Certificates." If it says "Waitlisted," you’re playing the waiting game again. You’ll be at the very top of the list, above everyone using the "complimentary" method.
Using the "Apply Each Segment" Strategy
One mistake people make when trying to figure out how do i request upgrade on delta is trying to upgrade the whole trip at once. Delta's system looks at "segments."
If you're flying Memphis to Atlanta to London, don't just look for an upgrade for the whole thing. You might be able to afford the upgrade for the long leg over the Atlantic but find the short hop to Atlanta is overpriced. In the app, you can often toggle specific legs of the journey.
Also, watch the "Comfort+" trap. Delta considers Comfort+ an upgrade. If you have status, you can set your preferences to automatically move you to Comfort+ as soon as you book. This is great for the legroom, but some people feel it "clogs" their chances for First Class. That’s a myth. Being in Comfort+ does not hurt your chances of getting into First Class later.
The Airport Standby List: The Final Frontier
Let’s say you did everything right. You checked the box. You have the credit card. You're still in the main cabin.
When you check in—exactly 24 hours before your flight—Delta will ask you again: "Would you like to join the upgrade list?"
Say yes.
Even if you already said yes months ago.
Once you check in, you are officially on the "Gate List." You can track your position in the Fly Delta app. It’s transparent. You’ll see "3 seats remaining" and your name at #4. It’s heart-wrenching. But here’s a pro tip: if the person at #2 or #3 doesn't show up by 15 minutes before departure, those seats go to the next people on the list. Stay near the gate. Don't be that person who misses their name being called because they were getting a Cinnabon three terminals away.
Why Your Fare Class Matters More Than You Think
When you ask how do i request upgrade on delta, you have to look at the letter on your ticket. It’s tucked away in the "Flight Details."
- Y, B, M are high-value tickets. You’re the priority.
- H, Q, K are mid-tier.
- L, U, T, X, V are the "deeply discounted" seats.
If you and another Gold Medallion are both vying for the last seat, and you bought a "T" fare while they bought a "K" fare, they win. Every time. If you really want that upgrade, sometimes paying $20 more for a higher fare class during initial booking is the secret sauce.

Realities of the 2026 Travel Climate
Flying is crowded now. Delta has gotten very good at selling those First Class seats for cash at the last minute. They’d rather take $100 from a non-status flyer than give the seat away for free to a loyalist. This is called "monetizing the premium cabin."
Because of this, the "complimentary" upgrade is becoming a "white whale" for many. If you see a buy-up offer in the app for an amount of money or miles that feels fair to you, take it. Don't wait for the upgrade list. The list is a gamble; the buy-up is a guarantee.
Summary of Actionable Steps
- Check your Fare Class: If it’s "E" (Basic Economy), you are ineligible for any upgrades, period.
- The "Request" Toggle: Ensure the "Request Upgrade" box is checked in your Delta SkyMiles profile preferences and double-checked during the booking process.
- 24-Hour Check-in: Check in the very second the window opens. While it doesn't move you past higher status tiers, it acts as a tiebreaker for people within your same tier and fare class.
- The App is King: Monitor the "Upgrades" tab in the Fly Delta app starting 48 hours before your flight. This is where the paid "upgrade offers" usually drop in price.
- Credit Card Buff: If you’re serious about Delta, the Amex Reserve card is basically a requirement for the upgrade "tiebreaker" boost.
- Call for Certificates: If you are using a Regional or Global Upgrade Certificate, don't trust the website entirely. Call the Medallion line to ensure the certificate is "open" and "attached" correctly to your PNR (Passenger Name Record).
- Gate Presence: Be at the gate 40 minutes before departure. If the gate agent is processing upgrades, being visible and polite can occasionally work in your favor if there's a last-minute seating shuffle.
