One bit of good news for members in the AAdvantage program changes that I haven’t seen get any play is that mileage upgrade award charts don’t appear to be changing.

Delta made upgrades a lot more expensive this year. United has many more upgrade price levels, including some more expensive than AAdvantage. But American hasn’t changed their upgrade prices.

Upgrades were once the best, most leveraged use of miles. But awards became more flexible (mix and match various alliance partners) while upgrades became more expensive (tons of miles and the introduction of cash co-pays).

United Will Charge You Up to $600 and 35,000 Miles Each Way

United introduced cash co-pays for upgrade awards in 2009. They actually matched American on this — American introduced cash co-pays first.

In mid-2011 United raised the cost of mileage upgrades and increased cash co-pays as well. They went from three fare categories — business class (except for discounted Z fares), full (Y or B) fare coach, and discount fares — to nine separate fare categories each with its own price in terms of miles and cash.

Here’s a portion of the upgrade chart for United flights:

Upgrades cost as much as 35,000 points and $600 each way.

Interestingly when United announced their brutal award chart devaluation in November 2013, they made some unpleasant tweaks to upgrade rules but didn’t change the upgrade chart.

Delta Will Charge You Up to 115,000 Miles Each Way — and Won’t Let You Upgrade the Cheapest Fares

Delta doesn’t permit upgrades on the cheapest fares at all. You have to buy at least a mid-tier K fare if you want an international upgrade. Here are one way upgrade prices with Delta:

US-Europe

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

US-North Asia:

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

US-South Asia, Micronesia, Southwest Pacific

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

Buy an expensive coach ticket and still spend 230,000 miles roundtrip between the US and South Asia for an upgrade. You’re paying cash for the ticket and spending a ton more than a saver award costs for a ‘free’ ticket. And yet international upgrades on Delta are still super hard to get.

American Charges Up to $550 and 25,000 Miles — and That Didn’t Go Up

American has four levels to their upgrade chart — from discount or full fare economy to business and from discount or full fare business to first.

They don’t waive cash co-pays on domestic mileage upgrades for elite passengers, so they aren’t as friendly as United on this. On the other hand domestic upgrades on all except for premium transcon New York JFK – Los Angeles/San Francisco are usually available.

I’ve always hated cash co-pays, but American’s are a bit cheaper than United’s and the mileage cost to upgrade is lower for American flights than United flights. In fairness to United, American’s international route network is more limited.

Confirmed upgrades at time of booking can be tough of course. But that American’s upgrade prices aren’t changing as part of the AAdvantage revamp and new award chart going into effect March 22 seemed worth noting.
