Slipstream

Guides

Everything you need to use points well — without becoming a points nerd. Slipstream handles the detail; these explain the ideas.

What are transfer partners?

Bank points like Amex Membership Rewards aren't airline miles — they move into airline programmes at a set rate that varies by partner — often 1:1, but not always, and some transfers take days to arrive. The trick is knowing which transfer unlocks the best seat. Slipstream does that comparison for you.

Should I transfer now or wait?

Transfers are almost always irreversible, so the golden rule is: only move points once you've confirmed an award seat. If Amex runs a transfer bonus, check its terms on Amex's site before topping up — it can be worth it if you're ready to book.

What makes a redemption 'good value'?

We score every option in pence per point — the cash value of the seat (minus taxes) divided by the points spent. Green is excellent, amber reasonable, red poor. Premium-cabin long-haul usually gives the most value per point.
