Avios vs AAdvantage miles
Close on value per point, far apart on what you pay in cash at the end. The comparison that actually decides a booking.
Avios and AAdvantage miles land close in value — about 1p per Avios against roughly 1.5 cents per mile — so the deciding factor is usually the cash charges, because a British Airways Avios reward adds carrier charges on top of tax. Avios expire after 36 months of inactivity; AAdvantage miles after 24.
Avios against AAdvantage.

| Expiry | 36 months of inactivity | 24 months of inactivity, except AAdvantage credit-card holders and members under 21 |
| Typical value | 1p per Avios | 1.5¢ per mile |
| Published range | 0.9p to 1.7p | 1.2¢ to 1.8¢ |
| Pricing model | Distance bands, repriced December 2025 | Set by American, with the two US reference valuations disagreeing |
| Cash on top | Taxes plus British Airways carrier charges | Taxes; surcharges vary by the operating partner |
| Best for | Short-haul Europe, and premium cabins where the rate stretches | US domestic and partner awards priced below the cash fare |
Lean Avios if…
- You fly British Airways, Iberia, Aer Lingus or Qatar often enough to earn them.
- You are redeeming in a premium cabin, where the rate reaches its top band.
- You can feed the balance from Amex or Nectar to keep the 36-month clock reset.
Lean AAdvantage if…
- Most of your flying is inside the United States.
- You want to avoid carrier charges stacked on top of the award.
- You hold an AAdvantage card or are under 21, which exempts you from expiry.
25,000 points, worked through
At the typical rates, 25,000 Avios come to about £250 of redemption value and 25,000 AAdvantage miles to about $375. Those are close enough that value per point is not what separates them.
What separates them is what lands on the card at the end. A British Airways Avios reward adds carrier charges to the tax, and on a long-haul premium seat that cash figure can run into the hundreds. Price the cash total, not just the points, before deciding which balance to spend.
Where these numbers come from: AwardWallet 36 months without collecting, spending, buying or sharing an Avios (September 2026); AwardWallet 24 months with no earning or redemption; cardholders and under-21s exempt (September 2026); Head for Points 1p as a ball-park, across scenarios from 0.87p to 2p (30 May 2026); The Points Guy 1.4 US cents (1 September 2026); The Points Guy 1.45¢ (1 September 2026); NerdWallet 1.7¢ (August 2026). Valuations are estimates and programs devalue, so treat every figure as the position on the date beside it and check the live price before booking.
How many Avios for a flight?
It depends on distance and cabin, not a fixed price. British Airways Club prices rewards in distance bands, so since the December 2025 repricing a short-haul economy reward starts at 10,000 Avios one-way, and business on the same routes runs roughly 16,500 to 26,750. Cash taxes and carrier charges are always extra.
What are Avios worth?
One Avios is typically worth about 1p, the working figure both the UK and US reference valuations settle near, so 10,000 Avios come to roughly £100. Weak via-hub economy redemptions land nearer 0.9p, while long-haul business can reach about 1.7p. The calculator converts any balance into pounds, dollars and euros.
What can my points do?
Add your Amex Membership Rewards to your Avios, since they transfer to British Airways at 1:1, and compare the total with off-peak reward prices. A New York–London economy return is 55,000 Avios and business 176,000. The tool sorts trips into within reach now, one transfer away and not yet in reach.
