Air New Zealand Air Points - are standbys allowed?

Are same-day international standbys generally allowed at the airport? Thanks.

Yes. If there is a seat you can buy it.

But it would be very very expensive.

A discounted ticket immediatly before travel are a thing of the past for most airlines now.

I think Seawolf may be asking whether you can standby on an earlier / later in the day having already purchased a confirmed seat on another flight on the same day.
