Not every ticket can be upgraded with Avios. This is the complete, cabin-by-cabin table of which British Airways fare codes qualify — and which are locked out for good.
An Avios upgrade turns a good seat into a great one for a fraction of the cash price — but only if your fare class allows it. Book the wrong bucket and no amount of Avios will move you forward. This table shows exactly where you stand before you buy.
Upgrades using Avios move you exactly one cabin up. The table below lists every British Airways revenue fare class and whether it can be upgraded, assuming a reward seat exists in the cabin above.
| Cabin | Fare codes | Upgradeable? | Upgrades into |
|---|---|---|---|
| First | F, A | No — top cabin | — |
| Club (Business) | J, C, D, R, I | Yes | First |
| World Traveller Plus | W, E, T | Yes | Club World |
| Economy (higher) | Y, B, H, K, L, M, N, S, V | Yes | World Traveller Plus |
| Economy (cheapest) | Q, O, G | Never | — |
Reward classes (economy X, World Traveller Plus P, Club U, First Z) are not shown because reward tickets cannot be upgraded using Avios at all.
The single most useful column is the fare codes. When you search a flight, British Airways shows a cabin name and a marketing label such as “Basic” or “Plus”, but the booking confirms a one-letter class. Match that letter to the table and you know instantly whether an upgrade is even possible.
Upgrades cost Avios, so the balance is what matters. A British Airways American Express earns Avios on everyday spending and builds towards a 2-4-1 companion voucher, stretching your points across two seats at once.

The mechanics, and why availability so often blocks an otherwise eligible ticket, are covered in how fare class affects upgrades.
