The British Airways Amex earns 1 Avios per £1. Whether it's worth the fee comes down to one question: do the perks and points you'll actually use add up to more than £0 a year? Here's what's on the table, plus a free tool to work out your number.
Companion Voucher (economy) — earned at £15,000 spend in a card year, valid 12 months. Spend £15,000 in a card year and a second passenger flies on the same Avios booking for no extra Avios: economy cabins only (Euro Traveller / World Traveller), on BA, Iberia or Aer Lingus. Flying solo? It halves the Avios instead. Valid 12 months. Default value £100: economy Avios prices are low and the short validity causes breakage.
Does it pay for itself?
There's no fee, so any value you get is upside; the real question is whether it's your best earner versus the alternatives. The free CCWorth adds it all up from your own answers and shows your real position, plus exactly what it'd take to break even.
