The Queen Mary 2 had to put back departure to ensure that passengers aboard weather delayed flights from the UK to New York were able to join the ship.
The ship is currently on schedule to arrive in Southampton on the morning of January 10 as planned.
Angus Struthers, Cunard's Marketing Director said "We're looking forward to celebrating Queen Mary 2's 10th anniversary of her naming with a tandem sailing from Southampton with Queen Elizabeth - the two ships will set off together on their respective World Voyages at 8.15pm on 10 January."
