I recently flew from New York-JFK to Paris (CDG) to cover France’s reopening to international tourists. While I booked a Delta Main Cabin economy class ticket, I ended up upgrading to Delta One using Delta SkyMiles.

Since the article published, I’ve been asked by several readers how I did this. So I figured I’d take a minute to outline how I upgraded my Delta flight from Main Cabin to Delta One.

I’ll run through my experience first and then discuss how you can upgrade Delta tickets too.

Upgrading from Delta one on a flight to Paris

I didn’t book my Main Cabin flight expecting to upgrade to Delta One. After all, my trip to Paris was for work and it wasn’t a flight review. I was looking for the most simple and cost-effective way to get to Paris on the day France reopened for tourism.

However, when I checked my flight 48 hours before departure, I noticed I had an upgrade offer on my flight. I could upgrade from standard Main Cabin economy to Delta One for $699 or 69,900 SkyMiles.

At first, I shrugged off the upgrade since it would give me less than TPG’s SkyMiles valuation of 1.1 cents per point. But then I thought a little deeper — it’s hard to get outsized value with SkyMiles these days due to Delta’s hyper-dynamic pricing on international business class awards. Even partner tickets have skyrocketed in price.

Most Delta One seats from the U.S. to Europe cost 100,000+ SkyMiles each way. That said, a Delta One award ticket would likely have been significantly more expensive since I booked less than a month from my date of travel.

Plus, my ticket was right around $350. This low cash cost (which was reimbursed anyway) made it easy for me to justify spending the miles on an upgrade. I don’t redeem SkyMiles frequently either, so it was nice to have a reason to use them.

One last thing: I’m chasing Delta Medallion elite status this year. Buy-up upgrades like this rebook your ticket into a higher class of service, so you earn more Medallion Qualifying Miles (MQM) on your trip. Plus, you’re eligible for the higher “accelerator” status boost offered to Comfort+, Premium Select and Delta One customers. This was another draw toward the upgrade for me.

Was upgrading to Delta One worth it?

I think the upgrade was absolutely worth the SkyMiles I spent.

We were originally booked on an A330-300, which has Delta’s older (i.e. not Suites) Delta One product. This would have been fine, since I’d still have a lie-flat seat offering a restful flight to Europe.

Thanks to a last-minute equipment swap, we actually flew an A330-900neo across the Atlantic. This is one of Delta’s newest jets and is equipped with true Delta One Suites, complete with a sliding door.

The service on-board was solid too. All meals were served on a single tray, but the flight attendants came around frequently to refill drinks. It was a good transatlantic experience and I arrived in Paris rested and ready to get to work.

How to upgrade to Delta One with SkyMiles

There are a couple of ways to upgrade tickets with SkyMiles. Here’s a quick look at how to upgrade Delta (and partner) Main Cabin tickets to Delta One business class.

Upgrading to Delta One after you book

The most common method of upgrading with Delta using SkyMiles to purchase a buy-up upgrade before check-in.

You’ll be offered a buy-up upgrade on your flight details page. Generally, an upgrade from Main Cabin to Comfort+, Premium Select, First Class or Delta One will appear above your itinerary alongside its cash and miles pricing.

For example, here’s a one-way flight I’ve booked from Chicago-O’Hare (ORD) to New York (LGA) early next month.

You can choose to book one of these right away or you can wait to see if pricing changes closer to departure. Travelers with Delta Medallion elite status may opt to see if they can score a complimentary upgrade too.

If no upgrades are available, you won’t see an option to upgrade.

Upgrading to Delta One when booking your tickets

You can also upgrade your tickets when booking a new ticket. You’ll see upgrade offers at check-out. These are generally bookable with points or cash. You will generally see upgrades to one higher class of service (Main Cabin to Comfort+ or Comfort+ to Delta One, etc.).

Are any of these upgrade options a good deal?

Now that Delta prices most upgrades dynamically, it’s hard to say if an upgrade is a good deal or not. It all depends on your specific situation. If a business class cash fare is high, but you can cover an upgrade with relatively few SkyMiles, it can be a good deal.

It’s also worth keeping your personal valuation of Delta SkyMiles in mind. If you value SkyMiles at well over one cent per point, you may want to save them for a future redemption that gets you more value.

However, I rarely get more than 1.3 cents per point from SkyMiles, so I don’t mind using them to upgrade tickets for a little added comfort on long flights. My rule of thumb with SkyMiles upgrades is to get at least one cent per point in value.
