FEDFUNDS Is Up. Does That Make American’s New Cash-and-Miles Deal More Useful?

The effective federal funds rate, tracked in FRED as FEDFUNDS, rose to 3.75% in September 2026 from 3.63% in August. That does not change the mechanics of American Airlines’ new "cash and miles" option for AAdvantage members, but it does sharpen the money question behind it: when borrowing costs stay high, is using miles to cut a travel bill now worth accepting weaker redemption value?

American Airlines has unveiled a new way for AAdvantage members to book flights: a "cash and miles" option that lets travelers split the cost of a domestic ticket between money and miles. Announced on October 2, 2026, the feature is expected to roll out in the coming weeks on aa.com and the American app.

For anyone sitting on an AAdvantage balance that is too small to cover a full award, that is the obvious appeal. The harder question is whether this is actually a good use of miles — or just a more convenient way to get less value from them.

The real trade-off is flexibility versus redemption value

American’s new option brings it closer to rivals such as Delta Air Lines and United Airlines, which already offer blended payment choices. But the early math looks notably weaker than a standard award booking.

According to The Points Guy’s October 2026 analysis, miles redeemed through American’s new blended option are worth roughly 1 cent each. That is well below the valuation The Points Guy assigns to traditional AAdvantage award redemptions.

That gap is the story. If you use miles this way when you could have booked a normal award instead, you are effectively accepting a lower payout for the same currency. American is selling the feature as added flexibility, and for some travelers that is true. But flexibility is not the same thing as value.

There is another catch for frequent flyers: only the cash portion of these bookings is confirmed to earn additional miles and Loyalty Points. That means members chasing status may be getting less redemption value while also limiting how much progress they make toward elite perks.

Who should actually use it — and who probably should not

The strongest case for cash and miles is simple: you do not have enough miles for a full award and would otherwise leave a small balance unused. In that situation, using some miles now may be better than waiting indefinitely to top up an account.

It may also work for travelers who care more about lowering an out-of-pocket fare today than maximizing every mile on paper. That is a real use case, especially in a higher-rate environment where cash can feel more expensive to part with.

But for members who already have enough miles to book a standard award, the new option looks harder to justify. Using The Points Guy’s October valuations, the blended option starts to resemble a convenience fee paid with your rewards balance.

In other words: this is most useful when your alternative is not a better redemption, but no redemption at all.

Why FEDFUNDS matters to this travel decision right now

This would be an easier feature to shrug off in a cheaper money environment. That is not the backdrop American is launching into.

The effective federal funds rate rose to 3.75% in September 2026, according to FRED official data. The Consumer Price Index rose 0.396% in August 2026, while the Personal Consumption Expenditures Price Index increased 0.31% in the same month. At the same time, the University of Michigan Consumer Sentiment index fell 6.34% in August 2026.

Those numbers point to a consumer still dealing with sticky prices, softer confidence and a policy-rate backdrop that keeps financing conditions relatively tight. That matters because loyalty points tend to feel most valuable when cash budgets are tight. A traveler deciding whether to spend dollars or miles is not making that choice in a vacuum. If flights are expensive, everyday costs remain high and money itself is not cheap, getting 1 cent of value from a mile instead of a higher value on a standard award is more noticeable, not less.

This is also why American’s timing is interesting. A feature designed around flexibility tends to look better when travelers are short on points, short on cash, or both. A higher FEDFUNDS backdrop does not make the redemption math better, but it can make the cash-saving pitch more tempting.

The next test is whether members treat this as a backup, not a default

The most important thing to watch is how travelers behave in this rate environment.

If AAdvantage members use cash and miles mainly to unlock trips they could not otherwise book, the feature fills a practical gap in the program. If members start using it as a default payment method without comparing it to standard awards, American has effectively introduced a more convenient but lower-value redemption lane.

That distinction matters because loyalty programs work best when members understand what they are giving up. In this case, the answer appears clear: in a higher-FEDFUNDS world, convenience may feel more valuable, but optimal value still probably lies with traditional awards.
