First Class Guide

Using a Companion Voucher in First Class

A 2-4-1 voucher can put two people in British Airways First for the Avios of one — the single biggest saving in the programme. Here is what it takes, and whether it is really worth chasing.

Last updated: September 2026 8 min read

First class is where a companion voucher saves the most in pure cash terms — but it is also the hardest cabin to actually book two seats in. This guide covers which card lets you do it, how much you really save, and the availability reality that trips up most people.

What you’ll learn:

  • Whether your voucher works in First at all
  • Which card you must hold
  • The scale of the Avios and cash saving
  • Why two First seats are so scarce
  • How far ahead to book
  • Whether First beats Club World for you

1. Can you use a companion voucher in First?

Yes — with one important condition. A British Airways companion voucher can be used in First class, but only if it was earned on the American Express Premium Plus card. That voucher is valid in every cabin. The voucher from the free British Airways American Express card is capped at economy and will not book a First seat.

As with any voucher redemption, both passengers must travel on the same flights in the same cabin, and you still pay the taxes, fees and carrier surcharges for both. The voucher simply removes the Avios cost of the second First seat.

First is the only cabin where the card you hold completely changes what is possible. If First is your goal, the Premium Plus card is not optional.

2. Which card you need

Only the Premium Plus voucher opens up First. It also lasts 24 months rather than 12, which genuinely matters here: because two First seats are scarce, you need the extra time to find them. On top of that, the card unlocks enhanced Club World reward availability on selected long-haul routes, giving you a strong fallback if First does not come together.

3. What it actually saves

First delivers the biggest absolute saving of any cabin. A return long-haul First reward seat can cost well over 100,000 Avios per person, so the voucher wiping out the second seat’s Avios is worth a great deal. In cash terms, two BA First seats on a premium route can list at more than £8,000, so the effective value is unmatched.

Remember, though, that the taxes and surcharges are also highest in First and are payable in full for both travellers — often several hundred pounds each. Use the companion voucher calculator to see the true net saving on your route, and read the surcharges breakdown before you commit.

4. The availability problem

This is where First redemptions live or die. British Airways releases only a handful of First reward seats, and you need two on the same flight. On many routes and dates, two simply are not available. Success depends on three things:

  • Booking early — reward seats are released around 355 days before departure, and grabbing two First seats often means acting the moment they appear
  • Being flexible on dates — off-peak days and shoulder seasons have far better odds
  • Being flexible on route — less popular First routes open up more readily than headline destinations

Our guide to finding Avios reward seats covers the search tools and timing tricks that make two-seat premium bookings possible.

5. Is First worth it — or should you pick Club World?

Ease of bookingHardStraightforward

Our take: if you can find two First seats and love the experience, nothing beats it for absolute value. But for most travellers, Club World is far easier to book, needs a smaller Avios balance, and still saves a small fortune. Don’t let a First seat that never appears leave your voucher unused.
