interesting replies I am actually asking this because I am doing a bit of "winter cleaning"! I have the tags in front of me and I am about to put them in the bin so just wanted to see what others think! Also, priority boarding as I would agree should only be reserved to silver and gold... bronze is way too easy to obtain.

Out of interest though, is priority boarding on international flights excluded to bronze card holders? I never hear them announcing it from LHR to HKG and definitely don't hear them calling out bronze or "ruby" on HKG airports.
