Late boarding time in Southampton

[BobBranst]

The schedule for our next BTB crossings from NY shows the departure time for Southampton as 9:00pm.   None of our previous scheduled departures from Southampton have been this late.  I would like to know the (latest) recommended reboarding time for in-transit passengers for this late departure time.

That is very late, it may be that there is an event onboard which means boarding will be later than normal.  I would check with Cunard.
