AA Miles Upgrades: Why the Math Rarely Works

AA's app now surfaces miles as an upgrade option right alongside cash. It's a clean UI with aspirational images of laughing passengers eating warmed nuts and toasting $7 sparking wine. What could go wrong? Unfortunately, in almost every case, a genuinely bad use of your AAdvantage miles. Here's the math on two real examples.

American Airlines has been expanding the ways you can spend AAdvantage miles over the past few years. Earlier this year they added merchandise, in previous years hotels & car rentals, and most prominently: in-app seat upgrades. If you book a Main Cabin seat and open the AA app, you'll often see buy up first class upgrade options. Alongside the cash upgrade price you'll also see a miles option front and center.

It looks like a convenient way to burn some AA miles. The problem is that when you run the numbers, the miles option is always a bad deal - sometimes a spectacularly bad one.

Here's what I've been seeing in my own offers recently, and what the math actually looks like.

The Short Hop: PIT–DCA

First example — AA 1473, Pittsburgh to Washington, one hour eleven minutes in the air. The in-app upgrade offer to First Class: $76 cash or 8,300 miles.

Run that through the MilesMate AA miles vs cash calculator:

• Cash price of upgrade: $76
• Miles required: 8,300
• Implied value: 0.92¢ per mile

The baseline I use for AAdvantage miles is 1.4¢. At 0.92¢ you're getting less than two-thirds of what AA miles are generally worth.

The cash option at $76 may be reasonable for some if you really value sitting up front - but the miles option at 8,300 is poor. You'd need the cash price to be around $116 for the miles to hit 1.4¢ value on this flight.

The Transcon: LAX–JFK

Now the one that really got my attention. LAX to JFK, 5 hours 30 minutes. The in-app upgrade offer: 173,400 miles to Premium Economy, or 467,700 miles to Business Class.

Let's deal with the Business Class option first. Let's be upfront though - both are spectacularly bad deals:

• Cash upgrade price: $4,274
• Miles required: 467,700
• Implied value: 0.91¢ per mile

It's almost exactly the same implied value on that short Pittsburgh hop, but at a much larger scale. AA's new XLR is nice - but not that nice for a domestic transcon!

Let's put it in perspective. Here's what 467,700 AAdvantage miles could actually buy on a partner carrier:

• A one-way business class award on Japan Airlines from the US to Tokyo runs 60,000–70,000 miles
• A one-way Cathay Pacific business class from the US to Hong Kong runs around 70,000 miles
• A one-way Qatar Airways Qsuites redemption from the US to Doha runs 70,000 miles
• A one-way Aer Lingus, British Airways, Iberia, Finnair, or Royal Air Maroc business class award from the US to Europe runs 57,500 miles

At 467,700 miles you could book six or seven one-way business class awards to Asia. Instead the AA app is surfacing it as a single domestic upgrade from Los Angeles to New York.

73,400 miles for Premium Economy isn't any better. That's two and a half transatlantic business class awards for a domestic cabin upgrade on a 5.5-hour flight. What would you rather choose?

The Reticketing Angle

There's a separate issue worth flagging that sometimes makes the cash upgrade price look bad too, independent of the miles valuation.

On certain routes and fare classes, the price AA charges for an in-app upgrade to First Class is actually higher than the difference between what you paid for your economy ticket and what a First Class fare would have cost if you'd just booked it that way from the start. In other words, the upgrade costs more than simply reticketing would have.

Here's the price to purchase a Flagship Business class ticket our LAX-JFK example above. You would save over $1,400 by purchasing a new ticket versus purchasing an in-app upgrade.

It doesn't happen every time, but it happens often enough that if you're looking at a cash upgrade offer that seems high, it's worth opening a second tab and checking what a First Class fare actually costs on the same flight. Sometimes you'd come out ahead just canceling and rebooking.

When Does the In App Upgrade Actually Make Sense?

Honestly, rarely. The math almost never gets to 1.4¢ on these in-app miles upgrade offers because the price is calibrated to what the market will bear, not to what your miles are worth. It is worth noting that the cash upgrade pricing can sometimes be reasonable. If you're looking for a deal, this is the place to start. Cash upgrades often start as low as $40 and sometimes in the low hundreds for haul international routes.

The AA app makes the miles option look like a easy choice by putting it right next to the cash price. That's intentional - the UI is designed to make redemption feel easy and comparable. Consider running the numbers through the AA Miles vs cash calculator - it will make the answer clear in a few seconds.
