How do I upgrade my seat on a Delta international flight

I actually went through this exact process a few months ago when I decided to upgrade my seat on a Delta international flight from Atlanta to Paris. I thought it would be a quick online thing, but as I learned, a few insider steps can make all the difference — especially if you want to snag a better seat for less.


So here’s how it went for me, and what I’d suggest if you’re in the same boat.


I’d booked my flight in economy about six weeks before the trip. At first, I wasn’t thinking much about comfort — I just wanted the cheapest fare. But as the trip got closer, the idea of sitting in a cramped seat for over 9 hours started to sound miserable. I checked Delta’s app first, hoping to see a simple “Upgrade” button next to my flight details. It did show options for Comfort+ and Premium Select, but the price difference was huge — nearly $800 for the upgrade! That’s when I decided to call Delta’s support line instead of just clicking through the app.


I dialed 877-297-0699, which I found to be the most direct number for Delta flight changes and seat upgrades. Honestly, I was surprised — I got connected to a real person within minutes. The agent was super friendly and knowledgeable. I explained that I wanted to upgrade to either Comfort+ or Premium Select, depending on availability and price. She checked and said there were still some Premium Select seats open, and since I was a Delta SkyMiles member, she could offer a discounted upgrade rate compared to what I was seeing online.


Here’s where it gets interesting: the phone rep told me that sometimes, Delta’s online system doesn’t reflect last-minute upgrade deals that agents can access directly. She refreshed her system, and suddenly a seat that was showing $800 online dropped to $550 when booked through her. I wouldn’t have known that if I hadn’t called. Within 10 minutes, she had processed the upgrade, reissued my e-ticket, and even helped me select my meal preference for the new cabin. Super smooth.


A few takeaways from my experience:

1. Always check online first, but don’t assume those are the only prices available. Sometimes calling 877-297-0699 gives you more flexibility and hidden offers.
2. If you’re close to your travel date (like within a week), upgrade prices can actually drop — especially on international routes with unsold premium seats.
3. Ask about using miles + cash. The agent I spoke with also mentioned I could’ve used part of my SkyMiles balance to offset the cost. I didn’t use it that time, but it’s a great option if you want an upgrade without paying full price.
4. Don’t forget that upgraded seats come with other perks — priority boarding, extra luggage, better meals, and way more legroom. On a long-haul flight, it’s worth every penny.

On the flight itself, I noticed an immediate difference. The seat reclined almost like a mini-bed, the service felt more personal, and I actually managed to sleep for five hours straight (which never happens for me on planes). The little details — noise-canceling headphones, better blankets, a welcome drink — really made the trip feel like part of the vacation, not just a tiring journey.


If you’re thinking about upgrading, my honest advice is: call first, confirm second, pay last. The agents can often see deals or availability that the app won’t show you. And if you need any kind of flight change — upgrades, cancellations, or even seat assignments — 877-297-0699 is absolutely the best line to reach Delta directly.

I actually upgraded my seat on a Delta international flight last year when I flew from Atlanta to Paris, and it was a pretty smooth experience once I figured out how it worked. Originally, I had booked a regular Main Cabin ticket because I was trying to save money, but as the trip got closer, I started thinking about how uncomfortable it might be sitting in economy for that long.


A week before my flight, I logged into my Delta account to check my booking and noticed there was an option to “Upgrade with Miles” or pay a little extra for Premium Select. Out of curiosity, I clicked on it to see the prices, and it turned out to be more affordable than I expected. I used some of my SkyMiles to cover part of the cost and paid the rest in cash. The upgrade went through instantly, and I got a new seat assignment right away.


On the flight, it was totally worth it—the extra legroom, better meals, and wider seat made such a difference. Since then, I’ve learned that Delta sometimes offers upgrade offers through email or at check-in too, so it’s always worth checking your account and the app in the days leading up to your flight.

To upgrade your seat on a Delta international flight, log in to Delta.com → My Trips, or use the Fly Delta App. Select your itinerary and look for “Upgrade with Miles” or “Upgrade Options.” You can upgrade using SkyMiles, cash, or complimentary Medallion benefits, depending on your fare type.

Eligible tickets can be upgraded to Premium Select, Delta One, or First Class (for transborder flights). The cost varies widely—sometimes from $300–$1,000 one way, or 20,000–90,000 SkyMiles, depending on demand and destination. For example, a U.S.–Europe upgrade to Delta One may start around 80,000 miles.

If no upgrades are available online, you can request one at the airport check-in counter or gate. Medallion Members are automatically added to the upgrade list. Booking a flexible fare and checking upgrade availability early maximizes your chances of securing a premium international experience with added comfort and exclusive service.
