British Airways has made some adjustments to their Companion Voucher program, particularly for long-haul flights. The minimum spend requirement to earn the voucher has increased, with the British Airways American Express Credit Card now requiring £15,000 spend and the Premium Plus Card requiring £15,000 spend. Despite these changes, the Companion Voucher remains a powerful tool for maximizing value long-haul business class flights, potentially saving travelers significant amounts of Avios premium bookings. British Airways' Companion Vouchers can yield up to 400% more value when redeemed for long-haul business class flights compared to short-haul economy redemptions. This disproportionate benefit makes strategic long-haul bookings particularly lucrative. The sweet spot for Companion Voucher redemptions often lies in off-peak travel dates to far-flung destinations.
