I have some inside information that BN is not the first consideration after tier for determining who is op-up'd.
Well whether they can technically upgrade you will also count... if you have BN1 but travel with a group, or travel with kids etc... and there are only 1 seat left in J... I guess you won't be upgraded... of course this is after tier.
