You can now use Delta miles to upgrade Comfort+ to First Class, but it’s not worth it

by on Tue January 10, 2017 • 1 Comment


You can now upgrade Delta Comfort+ fares to First Class with Delta SkyMiles, but you don’t want to do it.


Previously, only Economy Class tickets could be upgraded with miles.

The downer here is Delta agents are saying the number of miles you need to upgrade from Comfort+ is exactly the same as if you purchased an Economy Class ticket.

So, even though a Comfort+ ticket is more expensive, you won’t save on the mileage upgrade cost.

Basically with Comfort+ you’re buying an underlying Economy fare, with an upcharge for Comfort+, and that underlying Economy fare is what sets your upgrade price.

For example, here, the Comfort+ fare is linked to a ‘T’ Economy Class fare, which in the table below will cost 30,000 miles to upgrade.


Here are Delta’s upgrade prices for travel starting in the mainland U.S.:

Domestic / Canada

  • Y/B/M: 15,000 miles
  • S/H/Q/K: 20,000 miles
  • L/U/T: 30,000 miles


  • Y/B/M: 25,000 miles
  • S/H/Q/K: 30,000 miles
  • L/U/T: 35,000 miles


  • Y/B/M: 30,000 miles
  • S/H/Q/K: 35,000 miles
  • L/U/T: 55,000 miles

Europe, Southern South America, North Asia

  • Y/B/M: 60,000 miles
  • S/H/Q/K: 80,000 miles

Southeast Asia, Australia, Africa

  • Y/B/M: 80,000 miles
  • S/H/Q/K: 115,000 miles

Caribbean / Central America

  • Y/B/M: 15,000 miles
  • S/H/Q/K: 20,000 miles
  • L/U/T: 30,000 miles

Northern South America

  • Y/B/M: 30,000 miles
  • S/H/Q/K: 45,000 miles
  • L/U/T: 50,000 miles

These prices are nearly as high, or higher than you’d pay to book a full Business or First Class award with your miles. For example, to Europe you can often score a Business Class seat for 70,000 miles one way, instead of the 80,000 miles to upgrade a cash fare.

There are some decent ways to use SkyMiles, but this isn’t looking like one of them.

Basically the only time this makes sense is if you’re traveling for work, not paying for the ticket yourself, and your company won’t reimburse you for an upgrade with cash.

It’s a crummy value for your miles, and you’re better off saving them for an award on your own time.
