Your British Airways Executive Club tier is only the beginning. Behind the familiar Bronze, Silver and Gold labels sits an internal number called the Corporate Individual Value, or CIV — a score the airline assigns to every loyalty member and one that flight attendants can reportedly look up before or during a flight.

The system isn't officially acknowledged by BA, so most of what's known comes from the UK points blog Head for Points. The score runs from 0 to 105 and broadly maps onto the loyalty tiers: Blue members sit at the bottom with 0-5 points, Bronze gets 6-13, Silver lands between 14 and 35, and Gold members span a wide 36-96. Gold Guest List members and key corporate decision makers score 97-100, while Premier — BA's invitation-only top tier — gets a flat 105.

What's genuinely odd is the spread within tiers. Why does Gold cover 60 points while the tiers above Gold compress into just a handful? The assumption is that factors beyond status — spending, route mix, corporate value — determine exactly where you fall within your band. BA isn't saying, and crews are explicitly barred from disclosing a passenger's score, so don't expect an answer if you ask onboard.

Airline insiders will tell you passenger ranking is nothing new. Upgrade lists, irrops rebooking queues and standby priority have always been worked out via some combination of elite status, co-branded credit cards and lifetime spend. Plenty of carriers keep a customer value index tucked away in a reservations system. What makes BA unusual is the accessibility: pushing a raw score out to frontline cabin crew, rather than processing it in the background and handing staff a simple prioritised list, is a step further than most airlines go.

For travellers, the practical takeaway is modest but real. If you're a frequent BA flyer, the score likely influences the small discretionary perks — who gets an operational upgrade, who gets their first meal choice, who gets looked after when things go wrong. Flying more and holding higher status nudges you up the scale, which is roughly what you'd expect anyway. The main thing to know is simply that the ranking exists and is more granular than the published tier system suggests.

For everyone else, it's a reminder that loyalty programs hold more data than the tier brochure shows — and that the next upgrade you do or don't get may have been decided by a number you'll never be allowed to see.
