Thanks KARFA, and no problem Markie.
Maybe the alternative expectations around Golds and CE boarding at the same time arose as a result of the previous trials when various things seem to have been tried out, or slightly different interpretations are still being used by individual gate agents whilst the new system beds in.
I think the point about what happens when people are already queueing and waiting their turn is an unknown right now (and that queue invariably seems to form) - will it be necessary to run the gauntlet of muttering golds when CE boarding is called?
