What bonus can you get for adding a free Amex supplementary card to your account?

I wasn’t planning to do another American Express article this week, but something came up in the comments to the article on Monday (and comes up in my emails with worrying regularity) which made me think that we should take a proper look at American Express supplementary cards.  There seems to be some confusion about how they work.

Today I want to talk about the benefits of adding a supplementary cardholder to your Amex account and what bonus you will earn if you do.  A second article will explore the topic in more detail.

Why should you add a supplementary cardholder to your Amex account?

Reason 1 – it is easier to hit spending bonuses

The obvious first reason is that, by giving your partner a supplementary card on your American Express account, you can both focus your spending onto the same card.

This is especially useful if you are working towards a spend-based bonus, such as:

The 2-4-1 Avios redemption voucher on the British Airways American Express cards, which requires annual spending of £20,000 (free BA Amex) or £10,000 (the paid British Airways American Express Premium Plus)

The 10,000 bonus Membership Rewards points for spending £15,000 per year on American Express Preferred Rewards Gold 

It also makes it easier to trigger a sign-up bonus, such as the £3,000 in three months of spending required on the British Airways American Express Premium Plus card to receive the 25,000 Avios bonus.

Reason 2 – you can share card benefits with other people

If you have The Platinum Card from American Express, it is crazy not to use your one free Platinum supplementary card.  The person who gets it will receive:

a Priority Pass for airport lounge access

full travel insurance for themselves and their immediate family (now requires opt-in under new EU rules)

Hilton Honors Gold, Radisson Rewards Gold, Melia Rewards Gold, Shangri-La Golden Circle Jade and Marriott Bonvoy Gold hotel status

Eurostar lounge access etc etc

Even if you are single, you might want to issue a supplementary Platinum to a trusted friend or relative purely for the benefits.  My Mum had a supplementary Platinum on my account many years ago – I didn’t renew it when she hit 70 as the insurance no longer covered her – and my wife has one now.

You can issue further supplementary Platinum cards for £170 each per year.  This could be very good value for the right person given the Priority Pass and hotel status card benefits.

Note that not all Amex cards give all of their benefits to supplementary cardholders, so check the small print.

Reason 3 – you can double-up on ‘statement credit’ cashback deals

Many people do not know that the holder of a supplementary card can register it as a stand-alone card on the American Express website.

If my wife logs in to her Amex online account, for example, she can see her own Gold and BA Premium Plus cards as well as the supplementary card she has on my Platinum account.

Importantly, the supplementary card receives its own batch of statement credit offers.  This means that, if an offer appears on both your main card and the supplementary, you can register for it twice and earn it twice.

Reason 4 – you get bonus Membership Rewards or Avios for issuing a supplementary card

American Express now has a dedicated page on its website which you can use for issuing supplementary cards.  You can find it here.

The bonus is only paid on the FIRST supplementary card issued.  You will receive:

3,000 Membership Rewards points for issuing your first Preferred Rewards Gold supplementary card

5,000 Membership Rewards points for issuing your first Platinum supplementary card

3,000 Avios for issuing your first BA Premium Plus supplementary card

1,000 Avios for issuing your first free BA Amex supplementary card

There is NO bonus on the Costco, Harrods, Starwood or Nectar American Express cards.  There are bonuses on the two cashback cards.  The link for issuing supplementary cards is here.

Note that you WILL receive the bonus for issuing a supplementary card even if you did not qualify for a sign-up bonus when you originally applied for the card.

In Part 2 ….

Over the weekend we will look at the rules on getting American Express sign-up bonuses if you are already a supplementary cardholder.
