Pricing reflects British Airways one-way Avios and cash charges from London after the December 2025 devaluation and the May 2026 cash increase. Figures are indicative, so always check the live cost at ba.com before booking. This calculator prices one return ticket as two one-way charges, which is how BA prices most redemptions. Voucher value is calculated at 1p per Avios, the conservative benchmark. The 2-for-1 companion voucher comes from the two British Airways American Express cards at £15,000 spend in a card year: 24 months and any cabin on the Premium Plus, 12 months and economy only on the free card. You pay the Avios for one person and the taxes and charges for both. The Barclaycard Avios cards give a cabin upgrade voucher instead, which is a different benefit. First Class cash charges vary by route and search; treat those as a guide.

The voucher is one chapter. The Upgrade Blueprint covers every UK card worth holding, the 90-day plan, and real redemptions with the actual numbers I paid. Get the guide →
