Once you've earned a BA Companion Voucher and saved up 400,000 Avios, it’s time to think about where you want to go. First, a good tip is to make sure you’re getting good value from your Avios: aim to get at least 1p in value for each Avios you spend before you even use your voucher. This ensures you’re using your points wisely.
For this blog, let's talk about a Companion Voucher earned through the British Airways Club BA American Express Premium Plus card. Below is a list of the best places you can fly to with a Companion Voucher when you have 400,000 Avios to spend.
British Airways American Express Credit Card at a glance
The free British Airways American Express Credit Card earns 1 Avios per £1 spent, plus 5,000 bonus Avios after you spend £2,000 in your first three months. You get a Companion Voucher each membership year when you spend £15,000, redeemable on British Airways, Iberia, and Aer Lingus Reward Flights in economy, Euro Traveller, and World Traveller cabins subject to availability, with taxes, fees, and carrier charges per person.
The card has no annual fee and a representative 29.1% APR variable on purchases, with a 2.99% foreign transaction fee and a 3% cash advance fee. There are no intro balance transfer or annual fees, and a late payment fee of £12 applies where relevant.
British Airways American Express Premium Plus Card at a glance
The British Airways American Express Premium Plus Card earns 1.25 Avios per eligible £1 spent, including purchases with British Airways and BA Holidays. You can earn 30,000 bonus Avios after spending £6,000 in your first three months, and a Companion Voucher each membership year after you spend £15,000.
A note for anyone saving towards 400,000 Avios: the Premium Plus rates above are current on 8 September 2026, but both change on 7 October 2026. General purchases fall from 1.5 to 1.25 Avios per eligible £1, and British Airways or BA Holidays spending falls from 3 to 1.25. Recalculate any card-spend target that extends beyond that date rather than assuming today's earning rates will continue.
These vouchers are valid for 24 months and can be used in any cabin on British Airways, Iberia, and Aer Lingus Reward Flights, including Club (business) and First Class, with additional Club World seats often available when booking with a Companion Voucher, subject to availability. Taxes, fees, and carrier charges apply per person.
The card has a £300 annual fee and a representative 135.7% APR variable (29.1% variable on purchases, with a 36.3% cash advance APR). There is a 2.99% foreign transaction fee, a 3% cash advance fee, and a £12 late payment fee. There are no intro balance transfer or annual fees.
Business Class Destinations
Buenos Aires
Often called the "Paris of South America," Buenos Aires is a blend of European charm with a Latin twist. Picture streets graced with grandiose European-style architecture where cafes spill over with lively chatter and tango dancers stealing the show on the sidewalks.
You can explore colourful neighbourhoods like La Boca, where houses are painted in bright colours and the streets feel like an open-air museum. Or visit the San Telmo Market for a taste of local life, where you can find everything from vintage clothes to antiques and handmade crafts. And don’t forget to try some Argentine specialties like empanadas or the world-famous Argentine steak at a local "parrilla" (steakhouse). For the sports enthusiasts, there’s nothing quite like the electric atmosphere of a Boca Juniors football game at La Bombonera stadium. The local fervour for fútbol here can be felt deep in the bones.
If you’re thinking about visiting Buenos Aires and have a BA Companion Voucher with 400,000 Avios, here’s how you can use it: An off‑peak return flight in Business Class from London to Buenos Aires costs 210,000 Avios plus about £1200 in taxes and fees. This covers the Avios for one person’s fare, and the £1200 covers the taxes and fees for both passengers. You only pay the Avios for one ticket, but both of you can fly.
