There have been murmurings that the oneworld alliance needs a new top - tier elite level to accommodate (and further recognise) the very top elites from the various member airlines — this would see the likes of Concierge
Key and Premier
status holders separated out into their own new oneworld top tier (possibly called «Diamond»).
With airlines like American offering up to 5 elite
status levels (if you include the invitation only «Concierge
Key» level) and British Airways offering 3 official levels and possibly even a 4th and 5th (if you separate out Gold Guest List flyers and Premier card
holders) some have been questioning whether or not the oneworld alliance needs to add an additional tier.
